The laws of international exchange

Comparative costs
There is no proposition so central to orthodox
theories of international trade as the so-called
Law of Comparative Costs. From Ricardo to
Hecksher-Ohlin to Samuelson, in one guise or
another, the basic principle has remained un-
changed. Even the relentless search of neoclas-
sical economics for a state of perfect triviality
has not emptied this particular principle of its
content; from the time of its derivation by Ri-
cardo to its current incarceration in an Edge-
worth-Bowley Box, this law has continued to
dominate the analysis of international trade.
Even
-
and this is surely its greatest triumph to
date
-
even its public exposure as having been
all along the hidden law behind modern marriage
has not (yet) led to its complete discreditation?,
It is not surprising that a principle capable of
surviving “improvements’
such as the above
has managed to also withstand repeated attacks.
Before we touch upon these attacks, however, it
will be useful to briefly describe the law itself.
There are in fact two distinct propositions as-
sociated with this law, and the tendency to con-
flate the two has been a potent source of confu-
sion in the literature.
Let us begin by considering a country in
which cloth and wine are produced and sold at
the price ratio
(p,/p&
in the domestic market.
Across the channel is another country in which
cloth and wine are
alsn
produced and sold lo-
cally, generally at a different price ratio
(pJp&
than in the first country. Suppose the price ratios
are different. Then, if the price of cloth relative
to wine is lower in the first country than in the
second, the price of wine relative to cloth must
be lower in the second; that is, in each country
one commodity will be relatively cheaper.2
The first proposition is a prescriptive one. It
asserts that if each country were to export its
relatively cheaper commodity and import the
other,
c~?d
lj’ the terms of trade between cloth
and wine were to settle between
(p,./puJ1
and
(p,./~~)~,
then each country-as-a-whole would
gain from trade. That is, by concentrating its
production towards the relatively cheaper good
and exporting part of that good in exchange for
the other good, each country would end up
better off, in the sense that through trade a given
set of inputs could be translated into more out-
puts than before trade.
It is very important for our subsequent discus-
sion to note that the above proposition in no way
depends on the absolute costs of wine and cloth
in the two countries. Thus, even if one of the
two nations were absolutely more efficient in
producing both commodities
-
so that both wine
and cloth were absolutely cheaper in one
country than in the other3
-
“trade can be bene-
ficial if the country with the all-around inferior
efficiency specializes in the lines of production
where its inferiority is slightest, and the country
with all-aromd superior efficiency specializes in
the lines of its greatest superiority.” (Yeager,
1966, p. 4) Therefore, this proposition argues
that ij’under the right conditions (differences in
pretrade relative prices, the “correct” pattern of
exports, and an intercountry terms of trade in
the “appropriate” range), each country, no
mutter how hurckwwd its
techwlqy,
would
benefit from trade. Absolute costs are of no mo-
ment; all that matters is relative costs. Hence
the term “the principle of comparative
advan-

tage.
Taken by itself, the first principle says nothing
at all about what actually happens in interna-
tional trade. In fact, it would appear to be largely

irrelevant to the real process. Exports and im-
ports, after all, are undertaken by capitalists for
the sake of profit, not gains to the “nation.”
Profits, moreover, depend crucially on absolute
money costs: the lower-cost producer is always
in a position to beat out its rivals. In trade
between two advanced countries, each country
might be expected to have some absolutely effi-
cient producers, so
thrtt
in this case absolute ad-
vantage and comparative advantage coincide:
each country will then have one commodity for
which it is the lowest-cost producer and hence
the exporter. But how could a backward country
in competition with an advanced one possibly
hope to enjoy the “gains from trade” when both
its producers are the higher-cost producers‘?
This is where the second proposition comes
in. It is a descriptive proposition, for it asserts
that in free trade the patterns of trade
cr~‘N
in fact
be regulated by the principle of comparative ad-
vantage
-
regardless of any absolute differences
in levels of productive efficiency. The crucial
element in this step, therefore, is the presence of
some
crutomutic
mechunism
that will cause free
trade undertaken by profit-seeking capitalists to
converge to this result.
The sum of the two propositions is what is
generally called the “law of comparative costs”:
if permitted, free trade will end up

lute) advantage, and the resulting gains from
trade will be shared among the trading partners.
have been; the real point was that no nation need
be afraid of free trade, for it humbles the mighty
and raises the weak. Something like God, only
quite a bit more reliable.
The more recent formulation of the law, the
Hecksher-Ohlin-Samuelson
Zuny
oJ’
f&or
pro-
pnvtkms,
leaves intact the basic principle set out
by Ricardo. However, whereas Ricardo identi-
fied
the
real social cost of producing a commod-
ity as the total labor-time that went directly or
indirectly into production, the neoclassical for-
mulation insists upon defining the social cost(s)
of a commodity to the nation-as-a-whole as
being the commodities it (the nation) must
forego, at the margin, in order to produce an
extra unit of the commodity in question. Since
this concept of cost as opportunities foregone
cannot be used if there are unemployed
resources
-
for then any given commodity can
be produced without the national individual
(Uncle Sam) having to give up any others, that
is, without any opportunity cost
-
neoclassical
theory finds it necessary also to assume full em-
ployment. The assumption of full employment is
therefore just the,hidden dual of the concept of
opportunity cost.
In the original form given to it by David Ri-
cardo,
the crucial automatic mechanism was the
relation between the quantity of money and the
level of prices: the so-called
chsicul
yucrntity
theory
n$ money. In Ricardo’s famous example,
for instance, Portugal can produce both wine
and cloth more cheaply than England. Trade
between England and Portugal would therefore
initially be all in one direction, with Portugal ex-
porting both wine and cloth, which England
would have to pay for directly in gold since its
products were noncompetitive with Portugal’s.
But now the crucial equalizing mechanism
comes into play: the outflow of gold from Eng-
land is a decrease in its money supply and would
therefore lower all money prices in England;
similarly, the inflow of gold into Portugal would
raise all money prices there. As long as the trade
imbalance persisted, this mechanism would con-
tinue to make British wine and cloth progres-
sively cheaper, and Portuguese wine and cloth
progressively more expensive, until at some
point England could undersell Portugal in one of
the two commodities, leaving Portugal with the
relative advantage in the other. The exact deter-
mination of the terms of trade was understand-
ably not important to Ricardo, nor should it
The second distinguishing characteristic of the
neoclassical version is that, whereas Ricardo
bases the patterns of internatiorlal
sywiali~ation
on international differences in relative costs,
whatever their origin, the Hecksher-Ohlin for-
mulation attempts to tie the cost differences
themselves to a single dominant factor: the na-
tional endowments of labor and capital. Thus,
leaving absolute advantages aside, this approach
would argue that, given any two countries, the
capital-abundant country (the one having the
higher national capital-labor ratio) would tend
to be able to produce capital-intensive goods
relutively
more cheaply than the labor-abun-
dant country. Conversely, the labor abundant
country (the one having the lower national
capital-labor ratio) would of course have the
relative advantage in labor-intensive production.
It follows therefore that capital-abundant coun-
tries (read industrialized capitalist countries)
will and, for reasons of efficiency and the good
of the world-as-a-whole, should, specialize in
capital-intensive (secondary) products, ex-
porting them in return for the labor-intensive
(primary) products of the labor-abundant (un-
derdeveloped capitalist) countries: In other
words, the existing differences between devel-
oped and underdeveloped capitalist countries
are
effic~2nf
from the point of view of the
world-as-a-whole. Poor Ricardo dared only to
claim that free trade is better; neoclassical
theory can boldly claim that international in-
equality is best. No wonder that Gary Becker
206 Anwar Shaikh
found in this analysis so convenient an explana-
tion for institutionalized sexism (Becker, 1973,
1974).
What is perhaps most striking about the neo-
classical approach is that it completely assumes
away any possibility of absolute advantage on
the part of any one country: wine production in
England and wine production in Portugal are as-
sumed to be characterized by exactly the same
production function; similarly, cloth too has its
own universal production function. The central
thrust of Ricardo’s argument was of course that
free trade leads to gains even for countries that
are absolutely inefficient in comparison to their
trading partners; in the Hecksher-Ohlin version
all this is sacrificed to the need to prove that pat-
terns of international specialization are conse-
quences of the various national “factor endow-
ments
.’
It is interesting to note, however, that
when Leontief’s famous empirical test of the
Hecksher-Ohlin model appeared to refute it,
“Leontief rationalized this result by hypothe-
sizing that American labor is three times as pro-
ductive as foreign labor” (Johnson, 1968, p.
89)4
-
that is, he resorted to the argument that the
U.S. pattern of trade could be explained by its
absolute advmtuge over its trading partners! A
fuller discussion of Leontief’s study is at the end
of the next section, “Orthodox critiques.”
In general, modern presentations of the law of
comparative costs make no reference to the
actual mechanisms by which the law is to be
brought about. The emphasis is almost entirely
on the gains from trade that would be achieved if
trade were to be based on comparative costs;
nonetheless, because these ‘discussions are also
intended to be descriptive, “the implicit as-
sumption is [made] that the adjustment of money
wage and price levels or exchange rates required
to preserve international monetary equilibrium
do actually take place . .
.”
(Johnson, 1968, p.
84) As we shall see later, in the second major
section, modern derivations of comparative
costs rely on what are essentially variants of Ri-
cardo’s mechanism: in all cases, the very nature
of the desired solution requires monetary vari-
ables (price levels and/or exchange rates) to ad-
just in such a way as to transform absolute ad-
vantage into a comparative one. In all versions,
therefore, given England’s absolutely lower effi-
ciency and hence initially higher costs of pro-
duction, its ensuing trade deficit must somehow
result in a lowering of English prices while Por-
tugal’s trade surplus must lead to a raising of its
prices
-
until at some point each country has a
cost advantage in only one commodity.
The critique of comparative costs conse-
quently requires us to contrast four basic
theories of money: the Hume specie-flow ver-
sion of the auantitv theorv (Ricardo). the cash
balances version of the quantity theory, the
Keynesian determination of prices through the
level of money wages, and Marx’s theory
of
money. In order to do this, we need a common
ground of some sort.
Fortunately for us, most of the history of in-
ternational trade, and hence most of its theory,
has been dominated by precious metals as the
standards of both domestic and international
money.5 Thus, in discussions of the theories of
international trade, we always find a common
theoretical ground
-
their operation under the
so-called gold standard (The discussion of fixed
versus flexible exchange rates and their relation
to the gold standard is reserved for the second
major section). By contrasting various theories
on this basis, differences in the theories them-
selves may be separated from differences in
institutional arrangements. And because neither
the Ricardian nor the neoclassical versions of
the law of comparative costs claim to be depen-
dent on any specific monetary institutions, the
gold standard is a valid common ground. So
much so, in fact, that the neoclassical treatment
of the adjustment mechanism under the gold
standard is virtually identical to that of Ricardo:
“The adjustment mechanism under the gold
standard . . .was more or less automatic in
the sense that central banks were expected to
react to gold outflows and inflows by
more
restrictive and less restrictive monetary policies,
respectively, which would in turn react upon
price and wage levels, lowering them in the defi-
cit countries and raising them in the surplus
countries. These price changes, in turn, were ex-
pected to shift expenditure from surplus to defi-
cit countries, thus reducing and eventually elimi-
nating the disequilibrium . . . the theory is
correct in its broad outline even if its practice has
been somewhat oversimplified” (Mundell, 1968,
pp. 8-9).
We find, therefore, that, in spite of their much
discussed differences, the fundamental structure
of both the Ricardian and neoclassical versions
of the law of international exchange is the same:
in both cases it is relative advantage and not ab-
solute which determines the pattern of trade: in
both cases trade is mutually beneficial (or, at
worst, not harmful) to each country viewed as a
single classless entity; and, above all, in both
cases the mechanism which brings about the
successful operation of the law is essentially the
same.
Orthodox critiques
The law of comparative costs, whatever its
form, has always been associated with the advo-
cacy of free trade: Ricardo’s own development
The laws of international exchange
207
of this principle was in fact part of his polemic
against the corn laws (laws which prevented the
free import of cheap corn into England), and
from that time onward free traders of all kinds
have based their own arguments on those of Ri-
cardo.
It is not surprising, therefore, to find that
the primary thrust of critics has been to attack
not so much that part of the law which argues
that the pattern of trxle will depend
nn
cnmpra-
tive costs, as it has been to attack the proposi-
tion that free trade is efficient, mutually benefi-
cial, and good for the world-as-a-whole.
Frank Graham, for instance, focuses on the
assumption of constant cost, which he argues is
essential to the operation of the law; thus, by
working with combinations of increasing and de-
creasing costs, he is able to provide counterex-
amples in which free trade and specialization are
harmful to every one of the countries involved
(Emmanuel, 1972, p. XV)? In a similar vein,
Keynesians often attack the assumption of full
employment, which, as we have seen, is a neces-
sary complement of the nemlussicul versions of
the law; here, it is possible to construct coun-
terexamples in which hypothesized combina-
tions of unemployment and inflation may under
certain circumstances have a feedback effect on
the operation of the law and thus counteract it.7
Finally, there exists a whole series of modifica-
tions of the law, based on the analysis of interna-
tional differences in taste, on the existence of
tariffs and quotas, transportation costs, customs
unions, and so on.
In spite of their apparent opposition to the
law, all the above criticisms have this in
common: implicitly (and often explicitly), they
accept the law us being theoretically
vulid
on its
own grmnds. Instead, they seek to modify one
or more of these grounds so as to provide theo-
retical counterexamples. It is therefore not at all
surprising that these criticisms are usually
viewed not as refutations of comparative costs,
but rather as its further development; typically,
in neoclassical textbooks, the doctrine of com-
parative costs is presented as the fundamental
principle underlying international trade, with the
foregoing criticisms as extensions and concreti-
zations of it.
Orthodox critics, however, have yet another
recourse
-
attack by means of data. Here, the
two examples most often cited are the results of
Leontief s famous study (Leontief, 1953, 1956,
1958),
now known as the “Leontief paradox,”
and those of the Arrow-Chenery-Minhas-Solow
study, which gave rise to the so-called factor re-
versal issue (Arrow, et al., 1961). We will exam-
ine each in turn.
In the early 195Os, Leontief set out to empiri-
cally test the central proposition of the neoclas-
sical version of the law of comparative costs.
Beginning with the fact that the United States
was by all accounts a capital-abundant country,
Leontief reasoned that those goods which
America exported should be more capital inten-
sive than those which it replaced by imports.
What he actually found, however, was just the
opposite: “contrary to expectations United
States exports are more labor-intensive . . .
than
TJnited
States imports” (Johnson, 1968.
p. 88).
Neoclassical theory, it will be recalled, takes
it for granted that, in accordance with Ricardo’s
law, each country will export the relatively
cheaper commodity. What the Hecksher-Ohlin-
Samuelson model seeks to do is to go one step
further and argue that this relatively cheaper
commodity will in fact be the one which uses
proportionately more of the relatively abundant
factor of production: hence the theoretical ex-
pectation that the capital-abundant country will
export the capital-intensive commodity. In order
to make the above links, however, it is neces-
sary to assume away the possibility of absolute
advantage. In neoclassical terms, this means
that the production function for a given com-
modity, say wine, is assumed to be the same no
matter whether wine is produced in England or
in Portugal: thus wine could always be produced
at the same cost everywhere. It is not slqyising,
therefore, that, when faced with the unexpected
results of his study, Leontief was led to chal-
lenge precisely that assumption.
Leontief’s challenge did not go unanswered
for long. In 1961, Arrow, Chenery, Minhas, and
Solow published a study in which they argued
that cross-country comparisons of pruduc;tiun
functions did indeed indicate that American pro-
duction was systematically more efficient than
others: in other words, that the United States
had an absolute advantage (Arrow, et al., 1961;
see note 4 of this chapter). These results
prompted an investigation of the properties of
the Hecksher-Ohlin-Samuelson model when
production functions differ across countries,
which in turn led to the theoretical possibility
that capital-abundant countries might
t=xpur-t
labor-intensive commodities (Minhas, 1962).
Distressing as these results are to the propo-
nents of the Hecksher-Ohlin-Samuelson model,
they have little bearing on the principle of com-
parative costs, for (as we have already noted)
the model begins by assuming the Ricardian pat-
tern of specialization according to comparative
costs and then attempts to link this pattern to the
“factor endowments” of the nations involved.
At best, therefore, the above empirical and the:o-
retical paradoxes merely sever the attempted
link between national factor endowments and
the pattern of trade. They
leave
the Ricurdian
lcrw
untouched.
208 Anwar Shaikh
Finally, we come to those critics who attack
the law as being
yzo
Ic)pzgv~
valid, because one or
more of its premises no longer hold in today’s
world. Here, we find that the empirical criticism
of the law, and particularly of the efficacy of free
trade, is based on modem developments such as
the loss of wage and price flexibility, the demise
of the gold standard, the death of competition,
and systematic interference by governments?
For our purposes, it is sufficient to note that this
historical school of orthodox criticism (which,
as we shall see shortly, has its Marxist counter-
parts) implicitly accepts the law as valid where
its premises
-
primarily those involving competi-
tive capitalism
-
can be taken to hold. On its
own grounds (which in this case involve a partic-
ular historical epoch), the law is accepted as
*.
4
valid.
In sum, we find that so far as orthodox criti-
cism is concerned (whether it be theoretical,
empirical, or historical), the basic principles of
the doctrine of comparative costs emerge rela-
tively unscathed.
Marxist critiques
Given Marx’s exhaustive treatment of Ricardo’ s
theory of value, it would seem that Marxists
long ago have extended his analysis in one way
or another to deal with the Ricardian law of com-
parative costs. Curiously enough, this is not so:
instead, the issue is seldom mentioned (Mandel,
1968; Sweezy, 1942). Where it is discussed, Ri-
cardo’s attempt to determine the limits of inter-
national exchange is acknowledged only impli-
citly by accepting one of his central conclusions:
whereas the law of value regulates exchanges
within a competitive capitalist economy, it does
not do so between such economies (Sweezy,
1942, p. 289).
Why this striking silence? In part, it arises
from the fact that Marx himself never directly
accepts or rejects Ricardo’s principle of compar-
ative costs. This appears to be a puzzle until we
realize that,
w
Marx, RiCab93
r;hapte~-
on
foreign trade is essentially a special analysis of
merchant capital: “The great economists, such
as Smith, Ricardo, etc., are perplexed over mer-
cantile capital. . . .[Wlhenever they make a
special analysis of merchant’s capital, as Ri-
cardo does in dealing with foreign trade, they
seek to demonstrate that it ueutes no value (and
consequently no surplus-value). But whatever is
true of foreign trade, is also true of home trade”
(Marx, 1967, Vol. III, p. 324, emphasis added).,
Historically, of course, merchant’s capital
precedes industrial capital. But in the capitalist
mode of production it is industrial capital which
is dominant; Marx’s analysis therefore begins
with the latter and only arrives at the former
(merchant’s capital) in Volume
III
of Capital. It
is industrial capital which is involved in the pro-
duction of commodities, and hence in the
eye-
dorz of value and surplus value. Merchant capi-
tal, on the other hand, is involved in the trading
of commodities; it therefore accomplishes the
ttunsfer
of value and of surplus value, nationally
and internationally. It follows from this that in
order to understand its role within capitalist
(rather than precapitalist) modes of production,
merchant capital can be introduced only after
value and surplus-value have been properly
developed. Moreover, because the essential cir-
cuit of rucr&itut capital involves “buying cheap
and selling dear,” the question of the determina-
tion of prices is critical; and this in turn means
that money
-
the connection between value and
price, surplus-value and profit
-
must be ade-
quately developed prior to the analysis of mer-
chant capital. This last point bears repetition: a
correct analysis of the role of money is abso-
lutely crucial to an understanding of the laws of
commodity trade. This applies whether the
trading is done nationally or internationally.
It was of course Marx’s original intention to
extend the analysis presented in the three vol-
umes of
Cupid
to the treatment of international
trade and the world market, each to be dealt
with in separate volumes (Marx, 1973, p. 54).
But this never happened; instead, at the time of
Marx’s death even Volume III of Capitd existed
only as a “first extremely incomplete draft”
(Marx, 1967, Vol. III, p. 2). Nonetheless, as I
shall attempt to prove in this chapter, the devel-
opment of the law of value in Cupitd contains all
the necessary elements for its extension to inter-
national exchange. As we shall see, Ricardo’s
law
af
comparative costs follows immediately
from his law of value and his theory of money;
and Marx has provided us not only with detailed
criticisms of Kicardo on both value and money,
but also with his own formulations of these sub-
jects. The principal task of this paper is, there-
fore, to attempt an extension of the
Marxian
law
of value to international exchange.
The paucity of references in Marx to interna-
tional commodity trade is, however. only part of
the explanation for Marxist ambivalence on the
subject. Another, equally important, part lies in
the fact that ever since the publication of
Lenin’s
Irnperiulism
(Lenin, 1939) it has become
a Marxist commonplace to assert that capitalism
has entered its monopoly stage. Now, in the
case of monopoly, it is widely accepted by
Marxists and non-Marxists alike that laws of
price formation must be abandoned (Sweezy,
1942, pp. 270-l): “the most serious aspect of
The
laws
of
international exchange
209
monopoly from an analytic point of view, is that
the discr.epancies between monopoly price and
value are not subject to any general rules
(Sweezy, 1942, p. 54). What remain therefore
are the basic social relations of capitalist com-
modity productions, and it is to the various man-
ifestations of these that the theory of monopoly
capital turns.
Of course, Once the Jaws nf price formation in
general are thrown out, the laws of international
price formation necessarily follow. The focus
shifts instead to the domestic and international
rivalries of giant monopolies, to their political in-
teraction with various capitalist states, and to
the antagonisms and conflicts between these
states themselves
-
in other words, to imperial-
ism as an aspect of
mo~~opoly
capitalism. The
law of value, like competitive capitalism itself,
fades into history.
It is beyond the scope of this chapter to at-
tempt a proper construction of a Marxist con-
cept of monopoly, so as to confront the views
mentioned here. It must be noted, however, that
even an acceptance of the aforementioned views
in no way puts to rest the ambivalence among
Marxists with regard to Ricardo’s law, any more
than it resolves the recurring conflicts on the
transformation problem, the theory of wages,
etc.; instead, it merely sidesteps them? Like
their orthodox counterparts, these Marxist criti-
cisms leave the law of comparative costs still
standing
-
in the case of competitive capitalism,
at least.
Emmanuel and unequal exchange
In recent years, this whole issue has been once
again brought sharply into focus by Arghiri
Emmanuel’s challenging new work entitled
Unq44al
Exchange: A Study
of
the Impetkdism
uf Trade (Emmanuel, 1972). In this book, Em-
manuel sets out to overthrow the pernicious
doctrine of comparative costs by attacking what
he argues is its most fundamental assumption
-
the immobility of capital between different
countries. lo
In Ricardo’s original derivation of
the law, Emmanuel notes, Portugal is by as-
sumption absolutely more efficient than England
in both wine and cloth; hence, if Portugal and
England were mere regions of the same nation,
capital invested in Portugal would be consider-
ably more profitable, so that eventually the ab-
solute advantage of the Portuguese region would
lead to the cessation of both wine and cloth pro-
duction in the English region. But, says Ricardo,
Portugal and England are separate nations, and
in genera1 this erects significant barriers to the
mobility of capital between them, barriers which
he notes he would be “sorry to see weakened”
(Ricardo, 1951, p. 136). In Ricardo, therefore,
the analysis of flows between nations is essen-
tially confined to commodity flows, and it is his
contention that in this case Portugal’s absolute
advantage is of no lasting consequence; in the
end, only relative advantage matters, so that
each nation is assured of having at least one
exportable commodity to specialize in.
Emmund

its
OWM
grclunds (Emmanuel, 1972, pp. xxxii-iii). But,
he argues, its fundamental structure results from
the fact that Ricardo restricts his analysis to
those situations in which only commodities flow
between countries. The modern world, on the
other hand, is characterized by massive interna-
tional movements of capital, in addition to those
of commodities (Emmanuel, 1972,
p.
xxxiv). To
Emmanuel. therefore, the essential question is:
how do the international movements of capital
affect the previously valid Ricardian law of in-
ternational exchange ? In other words, what is
the appropriate form of this law in the modern
world?]
l
The emphasis on international capital
movements is of course not unique to Em-
manuel. In Marxist analysis of imperialism, for
instance, the internationalization of capital plays
an absolutely central role; even modern day pro-
ponents of the law of comparative costs often go
on to treat the issue of foreign investment and in-
ternational capital mobility. In general, how-
ever, these existing analyses treat capital flows
as a factor strictly separate from the laws of in-
ternational commodity trade (Kenen, 1968);
what Emmanuel proposes to do instead, is to
in-
tqg-ate thib ulvvtxnent into the law itsrslf and, by
so doing, separate the determination of the laws
of international exchange from any apologetic
for free trade. To Emmanuel, “modern free
trade” is characterized by both capital
tinci
com-
modity flows between nations. It is his avowed
intention, moreover, to demonstrate that it is
precisely the laws of this modern free trade,
which, when applied to the trade between devel-
oped capitalist countries and the so-called Third
World,
l2
give rise to a variely
0lY
phwwi~na
normally associated with the term “imperial-
ism” :
Imperialism is the highest stage of free
competition.
I3
The first step in understanding Emmanuel’s
analysis is to pose the question:
M?!ZJJ
does capital
flow between countries? And the answer, of
course, is because there exists a difference in
profitability between the countries involved. So
the question becomes, what are the intrinsic de-
terminants of this difkrence?
Let us begin with the selling price. In general,
international capital produces for the
~~~rld
market; if we ignore transportation costs (as
210
Anwar
Shaikh
being secondary factors in determining the pat-
tern of trade), then, no matter where production
is located, the selling price for a given type of
product is more or less the same
-
it is the world
market price. Moreover, because commodities
do flow between countries, technology is also in-
ternationally mobile: aside from transportation
costs, a given type of plant and equipment can
be located for more or less the same cost in any
country accessible to international capital.
l4
But
if the selling price is more or less independent of
the international location of production, and the
cost of a given plant and equipment is too, then
what gives rise to international differences in
profitability? The answer, it would seem, could
only be: the abundance of natural ,resources
and/or the cheapness of wage labor.
As long as the question is posed in terms of
WZJJ
two countries accessible to international
capital, it is not possible to narrow down the list
of factors any further. What Emmanuel has in
mind, however, is not the relation between just
any two countries but rather the relation
between developed capitalist countries of the
world and the so-called Third World, that is, the
underdeveloped, capitalist-dominated countries.
And in terms of this division of the capitalist
world, the overwhelmingly significant difference
arises from
the
rclativc
chcapncss
of wage labor
in the Third World. The United States is at least
as rich in natural resources as India, but it is not
uncommon to find Indian wages to be one-
twentieth those in the United States. Emmanuel
estimates that “the average wage in the devel-
oped countries is about thirty times the average
in the backward countries” (Emmanuel, 1972,
p. 48). According to Emmanuel, therefore, cap-
ital flows from the developed to the underdevel-
oped capitalist countries primarily to take ad-
vantage of the enormous difference in the cost
of labor-power.
We come now to Emmanuel’s analysis of the
effects of these international capital movements.
Wages, it will be remembered, are enormously
lower in the Third World, so that, other things
being equal, profit rates for local capitalists
would be very high. If local capitalists tended to
reinvest heavily, or if through government ac-
tion these profits could be taxed away and rein-
vested, high profit rates would imply a high rate
of growth of Third World countries
-
leading to
rapid development, a narrowing gap between
rich and poor countries, and, above all, do-
mestic control of domestic resources. Whatever
else was wrong, there would at least be no
imperialism.
l5
But the actual pattern appears to be the exact
opposite of the above; what we observe, Em-
manuel notes, is stagnation, a widening gap
between rich and poor countries, and wide-
spread foreign domination of Third World coun-
tries (Emmanuel, 1972, pp. 262-3). The major
cause of all this, he argues, is foreign invest-
ment: the very same low wage/high profitability
combination which
coulc2’
make rapid develop-
ment possible in the Third World is exactly the
factor that also makes these countries so very
attractive to foreign capital. Because foreign in-
vestment originates in countries in which the
average rate of profit is much lower than it is in
the Third World, foreign capitalists are generally
willing to accept much lower rates of profit than
local capitalists; they therefore invade local
markets, driving out local capitalists, drawing
down prices and thus lowering the average rate
of profit in the Third World. In this way the
surplus generated in the Third World is siphoned
off by foreign capital, to the detriment of the
Third World and to the benefit of the developed
capitalist countries. As a consequence, in the
developed capitalist world foreign investment
leads to higher profit rates, higher prices, and
higher growth: hence prosperity and full em-
ployment. In the Third World, on the other
hand, the very same movement results in low-
ered prices, lowered profits, and lowered
growth: hence stagnation, unemployment, and
foreign domination (Emmanuel, 1972, p. 265).
It is Emmanuel’s great merit to have revived
the important issue of the laws of price forma-
tion in international exchange, and in particular
to do so in a way that suggests that it is not nec-
essary to abandon the laws of competition in
order to be able to understand the intrinsic de-
terminants of modem imperialism. But there are
significant weaknesses in the manner in which’
Emmanuel himself deals with this issue. To begin
with, though he uses Marxist categories such as
value and surplus-value, the methodological
basis on which his work rests, and from which
he derives his implications, is fundamentally dif-
ferent from Marx’s; hence his political conclu-
sions, though radical, are as different from
Marx’s as were, for example, those of a rad-
ical contemporary of Marx
-
Pierre-Joseph
Proudhon.16
This, and the fact that his analysis
of imperialism runs counter to that of Lenin, has
led to a largely hostile reaction to his work
among some Marxists (Bettelheim, in Em-
manuel, 1972; Pilling, 1973).
Many of the criticisms of Emmanuel are quite
telling. But the challenge implicit in his work re-
mains unanswered by those Marxists who are
content to merely locate the distance between
Emmanuel and Lenin.
I7
These little exercises,
however illuminating, manage to neatly avoid
two central questions. First of all, at the level of
abstraction that Marx maintains in his three
vol-
212 Anwar Shaikh
foreign capital, and only insofar as it is to its own
benefit. This, as we shall see, will have impor-
tant implications.
A note on the structure of this chapter
In order to undertake the criticism of the law of
comparative costs, we must first see precisely
how it is derived. The second major section
therefore contains a brief exposition of Ri-
cardo’s theory of value, his theory of money,
and then of their interaction in the infamous law.
The next step is to set up a similar path in
Marx. In the third major section, first Marx’s
theory of value (and his criticism of Ricardo’s) is
outlined, and then his theory of money (with his
criticism of Ricardo’ s).
The first part of the fourth major section
unites the two theories in overthrowing the Ri-
cardian law of comparative costs: that is, we see
that when taken together they imply a determi-
nate theory of international exchange which
flatly contradicts Ricardo’s law
OYI
its very
owy1
grounds. It is in this section that the intrinsic
cause of international uneven development is
seen to be free trade itself, quite independently
of the traditional villains such as monopoly,
foreign investment, political power, etc.
The second half of the fourth major section
takes up the question of the export of capital.
Here, it becomes possible to see how and why it
is the very unevenness of development (as it is
reproduced and deepened by commodity trade),
which in turn posits foreign investment as both
the salvation
n~ci
at the same time the damnation
of the underdeveloped capitalist countries. It is
also possible at this point to see not only why
Emmanuel’s analysis of imperialism is incorrect,
but also why his proposed solution would be
useless.
At all times it is important to keep in mind that
the very structure of the theory of international
trade necessitates an introduction to theories of
value and theories of money before we can even
begin the analysis of trade. Obviously, to do jus-
tice to Ricardo or Marx on either of these scores
could easily require volumes. And yet, we must
cover both value and money, in both authors, if
we are to proceed at all!
Within the confines of a chapter this task can
be undertaken only if one sticks to the bare es-
sentials. Consequently, in what follows, brevity
has been attempted in the exposition of Ri-
cardo’s and Marx’s theories. Particularly when
dealing with Marx, it is a great temptation to not
only present and document the relevant struc-
ture of his analysis but to also defend it against
the misrepresentations which are so popular
(and so convenient) with orthodox theorists, or
at least to contrast his analysis with theirs.
Nonetheless, I have tried to avoid doing this: the
primary comparison which can properly be
made here, and that only in a largely expository
way, is the one between Ricardo and Marx. The
rest must await another occasion. But let this
much be clear: what follows is definitely not in-
tended as a mere exercise in the history of eco-
nomic thought. So-called modem economic
theories of value and money are no more ca-
pable of withstanding Marx’s criticism than
were the classical theories. In a sense, the oppo-
sition between Marx and Ricardo explored in
this paper is the historical prelude to the more
modern confrontation.
R
icardo’s derivation
comparative costs: of the law of
The Ricardian law of price. Ricardo held that the
principal problem facing political economy in his
day was the determination of the laws which reg-
ulate the distribution of the product of (capital-
ist) society among the three great classes: that
is, the laws which determine “the natural course
of rent, profit, and wages” (Ricardo, 1951, p. 5).
But very soon in the course of his work Ri-
cardo realized that his analysis could not pro-
teed without a theory of price:
Before my readers can understand the proof I

theory of currency and of price . . . If I
could overcome the obstacles in the way of
giving a clear insight into the origin and law of
relative or exchangeable value I should
have
gained half the battle. (Ricardo, 1951; pp.
xiv-v)
Ricardo’s battle was never completely won;
the question of the law of relative prices was to
trouble him to the very end. But it is a measure
of his greatness that the problems he posed have
persisted in one form or another down to the
present.
In order to appreciate the gains made by Ri-
cardo we must carefully follow his line of rea-
soning. The problem he set himself was the
determination of the luws which regulate relative
prices. Now of course he was well aware that
the immediate determinants of market prices
were supply and demand; but over the course of
time the ceaselessly fluctuating interplay of
supply and demand was itself regulated by a
more fundamental principle: equal profitability.
Thus, if as a result of market conditions a partic-
ular sector’s rate of profit rose above the
average rate, then the flow of capital would tend
to be biased towards that sector, causing it to

grow more rapidly than demand, and driving duction of the inputs required to produce these
down its market price to a level consistent with inputs, and so on, then the total labor time h, re-
average profitability. Conversely, the sectors quired to produce one unit of commodity A is
with low profitability would tend to grow less the sum of its direct labor requirement 1, and its
rapidly than demand, causing their prices and indirect labor requirements

lat2),
. . . etc.
profitability to rise. (Sraffa, 1963, pp. 34-5).
The classical economists were thus able to
demonstrate that behind the continuously
varying constellation of market prices there lay
another set of more fundamental prices, acting
as centers of gravity for market prices and em-
bodying more or less equal rates of profit. The
name given to these regulating prices in classical
political economy was “natural prices,” what
Marx was to later call “prices of production.”

On the other hmd, Sraffa points out that if w

(13.2)
All this was well known long before Ricardo’s
time. What then was he searching for? Certainly
not the means by which to calculate the prices of
production. Ricardo exhibits many such calcula-
tions himself, in the process of investigating his
greater problem; so it is clear that a system of
calculation, no matter how elegantly set out in
terms of matrices and vectors, would differ only
in form from the arithmetic relations set out by
Ricardo. What Ricavdo sought to do was some-
thing considerably more meaningful: to get be-
hind prices of production, to discover their
r;t;nters
of gravity.
That is, just as the market
price of a commodity was shown to be regulated
by its price of production, Ricardo sought to
show that this regulating price was itself subject
to a hidden governor
-
the total quantity of labor
time required to produce the commodity, both in
its direct production process and, indirectly, in
the production of its means of production.
The preceding equations illustrate the impor-
tance of direct and indirect labor requirements:
their simple sum is the total labor requirement
A~,
and their weighted sum is the price of pro-
duction
pa.
We come now to the critical point in the Ricar-
dian argument. In effect, what Ricardo argued
was that even though both the labor require-
ments and their weights (the wage-profit combi-
nations WJ) enter into the calculation of prices
of production, they are not equally important in
causing changes in these prices.
“In speaking . . . of the exchangeable value
of commodities, or the power of purchasing pos-
sessed by any one commodity, I mean always
that power which . . . is natural price” (Ri-
cardo, 1951, p. 92).
“The great cause of the variation in the rela-
tive value of commodities is the increase or
diminution in the quantity of labour required to
produce them” (Ricardo, 1951, p. 36).
There we have it: the great cause of the varia-
tions in the price of production of a commodity
is the variation in the total labor time that goes,
directly or indirectly, into its production. The
total quantity of labor time was the center of
gravity of the commodity’s price of production,
just as this price was itself the center of gravity
of its market price. This was Ricardo’s attempt
to formulate a second great law of prices.
Let me illustrate the logic behind this. Sraffa
(1960) has shown that if one unit of some com-
modity A requires
1,
worker-hours for its direct
production, 1,(l) for the production of its physical
inputs (machines, raw materials),
1,(2)
for the pro-

and
r.
First, as Sraffa so
elegantly demonstrates, a rise in the wage rate
w
is necessarily accompanied by a fall in the rate of
profit
r
(Sraffa, 1960, pp. 39-40) so far as rela-
tive prices are concerned. Therefore, Ricardo
argued that on the average the opposing move-
ments of these two weights would tend to cancel
each other out (Ricardo, 1951, p. 35-6). Fur-
thermore, it was his belief that in any case the
wage rate, being such a fundamental social
parameter, is only susceptible to relatively small
variations (Ricardo, 1951, p. 36): it is, as Keynes
was later to say, “sticky.” Last, Ricardo was
careful to point out that the net effect of a rise in
the wage rate and a corresponding fall in the rate
of profit varied from commodity to commodity:
whereas, it might raise some prices of produc-
tion, it would lower others, and leave others still
unchanged, so that it would have no determinate
effect on the direction of change of any given
commodity price (Ricardo, 1951, p. 46).
We turn next to the remaining factor
-
changes in labor requirements. Since any one
commodity is only one of literally hundreds of
thousands, an improvement in its conditions of
production is not likely to have much of an effect
on the general sot al parameters WJ. Any such
improvement will, however, in general reduce
its price bY lowering it s total labor requirement

quirements

. . . , etc.; or it will do
both.
Of course, a lower price for commodity A
might lower costs for other commodities, and
hence their prices too. But it is intuitively plau-
sible that these feedback effects will not in gen-
eral be greater than the original, so that the net
effect
1s
a lowering of the commodity’s price rel-
ative to the average: a reduction in the total
labor requirement A, of a commodity would be
associated with a reduction in its equilibrium
price pa.
In estimating, then, the causes of the varia-
tions in the value of commodities, although it
would be wrong wholly to omit consideration
of the effect produced by a rise or a fall of real
wages, it would be equally incorrect to attach
much importance to it; and consequently, in
the subsequent part of this work, although I
shall occasionally refer to this cause of varia-
tion, I shall consider all the great variations
which take place in the relative price of com-
modities to be produced by the greater or less
quantity of labour which may be required
from time to time to produce them. (Ricardo,
1951, p. 36)
Ricardo is true to his word. In the chapters
that follow he ignores the secondary variations
in prices by simply assuming that relative prices
are more or less equal to relative labor-times.
Both the analysis of money and that of foreign
trade is conducted on this basis.
It should be very clear from the above, inci-
dentally, that Ricardo’s law of prices in no way
depends on the “assumption of a single factor of
production” (Johnson, 1968,
p.
85),
as is so
often asserted. It is hard to believe that anyone
who has ever read Ricardo can make this claim;
even for a mind steeped in the marginalities of
neoclassical thinking it must be difficult to con-
front Ricardo and come away with nonsense like
that. lg
The classical quantity theory of money. Having
analyzed at great length the causes of the varia-
tions in relative prices, Ricardo then proceeds to
the causes of variations in the level of (money)
prices. For reasons outlined previously, we as-
sume (as does Ricardo) that gold is the money
commodity.
The money price of a commodity is of course
its relative price expressed in terms of the
money commodity; that is, its rate of exchange
with gold. Thus, the price of steel is so many
units of gold; normally, when gold is used as
money, there arise special names for specific
weights of it. In England around Ricardo’s time.
for instance, roughly a
l/4
ounce of gold was
known as a pound (f). A quantity of steel ex-
changing for
l/2
of an ounce of gold would
therefore be said to have a “price of
&2.
By the Ricardian law of prices, all commodi-
ties exchange roughly in proportion to the total
labor-times required for their production. It
follows, Ricardo notes, that the money prices of
commodities are determined by the quantities of
the labor-times requiwd for their production rel-
ative to the quantity of labor-time required for
the production of gold. Of course, gold cannot
have a money price in this sense, since it is
money. But to Ricardo, the quantity of steel (or
corn, or cloth, etc.) purchased by
&l
(l/4
oz) of
gold could be viewed as a “commodity price” of
gold. He therefore often refers to the “value” of
gold.
Suppose it takes 100 worker-hours to produce
a ton of steel, and that in a given year 4,000
tons are produced. The steel will then require
400,000 worker-hours. If it takes l/2
worker-
hours to produce
&l
(l/4
oz) of gold, then the
money price of the year’s steel output will be
f800,000.
Steel, however, is only one of a whole range
of commodities produced in a given year. During
any one year, therefore, the same gold coin may
change hands several times, being received by
one person through the sale of a commodity and
then being given over to someone else when it is
used to buy another commodity. In this way the
same gold coin can function as money more than
once, in a given year. Let us say that on the
average a coin changes hands five times a year;
its velocity of circulation is then five.
Imagine now that the labor-time required for
all the commodities produced in a given year is
40 million worker-hours. Since we stated pre-
viously that
&l
(l/4
oz.> of gold requires
l/2
worker-hours, the money price of the society’s
yearly output will be
&80
million. Moreover, if
the velocity of circulation of
f
coins is indeed
five, this means that only 16 million gold coins,
each weighing
&l
(l/4
oz) will be required as
/
money in that year.
Of course, the laws discussed so far apply
only to prices of production. We know from the
laws of market prices, however, that if a com-
modity’s supply exceeds its demand, then the
market price of the commodity will fall, that is, it
will exchange for less of other commodities. If
this law is also applied to money it leads straight-
away to the proposition that when the quantity
of gold coin exceeds the requirements of circula-
tion (the demand for coin), the “price” of gold
will fall. Now, since gold is money, it cannot
have a money price; however, since it can be
used to Purchase anv commoditv on the market.
it can be said to have literally thousands of
“commodity prices
,’
these being the quantities
of the various commodities one can buy with
&I
(l/4 oz) of gold. The quantity theory of money
therefore asserts that when the quantity of gold
cuin exceeds the
requirt=meriCs
of circulalion,
afI
the commodity prices of gold will fall; since this
means that gold
wit1
purchase less of each com-
modity, it is equivalent to asserting that all
money prices will rise.
If we consider England as a closed economy
with gold produced within its borders, then the
reduced price of gold
-
the higher prices of all
other commodities
-
would, according to Ri-
cardo’s
theory, result in reduced output from the
goMmines.
This reduction in the supply of gold
would in turn eventually raise its price, so that
once
again gold would exchange against other
cnmmcbditie,s in
pmportinn
tn
th4=%-
respxt~ve
labor- times.
If instead, gold were produced in a foreign
country like South Africa, then to say that the
“price” of gold in England has been lowered is to
say that its purchasing power over commodities
has been reduced. Gold will therefore have dif-
ferent purchasing powers in different countries,
and will flow out of England into countries
where its “price” is higher; once again, the effect
will he to lower the quantity of money in Eng-
land, and hence raise the “price” of gold back
towards its natural level. In this way the interna-
tional Aows of gold would lead to more or less
the same purchasing power of (gold) money in
all countries. This conclusion of the classical
quantity theory of money is known as the doc-
trine of “purchasing power parity” (Johnson,
1968,
pe
92).
The law of internationa1 exchange. The critical
element in Ricardo’s law of comparative cost is
really the quantity theory of money, because it is
through its operation that the law is derived.
However, in order to follow Kicardo’s analysis,
we
wiU
also use his law of prices.
Let us begin by considering two commodities,
cloth and wine, produced in England; cloth re-
quires 100 worker-hours to produce, and wine
120 worker-hours. If, as in our previous ex-
amples,
&I
(l/4
oz) of
goId
required 3/2
worker-hour to produce, then from Ricardo’s
law of prices the prices of production of cloth
and wine would be more or less equaJ to their
respective labor-times relative to that of gold.
Cloth would sell at about
~5200,
and wine at
about
X240,
domestically.
Consider now the same two commodities in
Portugal. The unit of money in Portugal we take
to be an
VSCU&I
(e.), roughly
116
of an ounce of
gold; assuming the same labor-time for gold in
Table

all countries, one escudo Cl/6 oz) of guld would
then require
l/3
worker-hours to produce. If
then in Portugal cloth took 90 worker-hours, and
wine 80 worker-hours, their domestic prices of
production would be roughly 270 e. and 240 e.,
respectively.
But note that both Z’s and e.‘s are merely dif-
ferent national money-names for quantities of
gold. If England’s payments to foreigners ex-
ceeded its
receipts
from them, that is, if it
Tan
St
balance of payments deficit, gold bullion would
eventually have to be used to make up the dif-
ference.20 Since both currency units are actually
quantities of gold, and the international means of
payment is in fact gold bullion, we can consider-
ably simplify the exposition by expressing all
prices directly in ounces of gold. Given that an
ounce of gold requires two hours of labor-time,
we have the following Ricardian tableau for Eng-
land and Portrrgal (Table 13.1).
Clearly, in this initial situation Portugal’s
greater efficiency in production translates
directly in an absvllrte adljantctge in trade. If
transportation costs are not prohibitive, Por-
tuguese capitalists will export both commodi-
ties. England will experience a continuing bal-
ance of trade deficit, which will have to be made
up by shipping gold to Portugal.
According to Ricardo, it is at this point that
the quantity theory of money becomes crucial.
The outflow of gold from England is a decrease
in its domestic supply of money,
so
that ac-
cording to the quantity theory the goid prices of
lrll English commodities will begin to fall. Con-
versely, the inflow of gold to Portugal will raise
alI prices there. As this happens, Portugal’s
competitive edge in international markets will
gradually erode, even though it will of course
have just as great an advantage in terms of effi-
ciency as it did before. It is just that this greater
efficiency will be increasingly offset by the rise
in Portuguese prices relative to those in Eng-
land.
Sooner or later In this process one of the two
English commodities will become just competi-
tive with its Portuguese counterpart. But which
one? Well, in terms of efficiency, England al-
ways has an absolute disadvantage relative to
Portugal in both commodities. But as all English
prices fall and all Portuguese prices rise, the
216 Anwar Shaikh
English commodity with the smnllust disadvan-
tage will be the first to overtake its Portuguese
rival. If we examine the Ricardian tableau,
(Table 13.1) we
fmd
that English wine produc-
tion is only 66 2/3 percent as efficient as its Por-
tuguese rival (since Portuguese wine takes
80
hours and English wine takes 120 hours),
whereas English cloth production is 90 percent
as ef~cient as Portuguese* England’s smallest
disadvantage
JI
its
~~~~~~~~?~
advantages lies in
cloth, and as English prices drop relative to Por-
tuguese, it is English cloth which first becomes
competitive. By the same token, it is clear that if
England has an equal disadvantage in both
sectors of pr~ductiun then both English eom-
modities would become e~mpetitiv~ at exactly
the same point. Though trade could still take
place under these cireumstances~ there would be
no fixed basis fur specialization* Only if England
has different disadvantages in the two eommodi-
ties, that is, only if it has a relative advantage in
one, can Ricardian trade take place?
Once England can compete in cloth, two-way
trade will begin. This will improve England’s
trade picture, but it will probably not eliminate
the deficit; price level movements will therefore
continue to take place, strengthening England’s
international position and weakening Portugal’s

with each country exporting the
one commodity in which it
HOW
has a relative ad-
vantage. If for some reason the adjustment
process goes too far, to the point where even
English wine undersells Portuguese, then the en-
suing gold flows would reverse the price level
movements until once again relative advantage
reigned.
An important implication of the process of ad-
justment is that in the end each country’s inter-
national terms of trade (the quantity of imports
that can be bought with a unit of its exports) will
necessarily be better than its domestic, In Eng-
land, for example, the cloth on the market will
be English cloth; but the wine available will gen-
erally be imported from Portugal. Those whose
unbounded patriotism would require them to in
sist on English wine will have to pay a higher
price fur it than they would for the imported
variety* Therefore, a unit of cloth, England’s ex-
port commodity will be worth more units of
Po~uguese wine than it will be
af
domestic wine
simply because domestic wine costs more. Simi-
larly, in P~~ugal, its export, wine, is worth more
units of English cloth than it is of Portuguese
cloth simply because the English cloth is
GhtXpX.
The proposition just forwarded, on the terms
of trade of each country has often been used as
the basis of a proof that each nation-as-,a-whole
gains from trade. Thus it is said that England can
get more wine for its cloth through trade than it
can get domestically: trade is generally benefi-
cial. Though Rieardo is careful to derive the
laws of trade on the basis of its profitability to
capitalists, when he turns to the analysis of the
effects of trade he abandons the concept
of
classes and reverts to that of a
natiun-as-~-
whole. Now, it is undeniable that the concept of
a nation is both valid and necessary at some
level of analysis; nations do exist and their in-
teraction is a real process. But to assert that
trade is beneficial to the nation-as-a-whole is
simply to assert that ‘“what’s good for General
Motors is good for the US.” Trade is under-
taken by capitalists because they can make more
profits that way; it is they who always gain.
Even if this gain for the capitalists happens to
spill over to workers in either country, which is
certainly not necessary from the above analysis,
one can only say that in this instance trade also
benefits a particular set of workers. It is not pos-
sible to reduce the fundamentally antagonistic
relations of classes to the bland homogeneity of
a nation-as-a-wholes Christians are not in a posi-
tion to cheer for lions as long as they are both
booked to play in the Coliseum.

of the law, It should be ubvi-
ous from the preceding derivation how crucial
the “right” sort of monetary theory is to the
derivation of the law of comparative costs. Any
monetary theory which translates the initial
trade deficit of the backward country into falling
price levels (falling relative to the price level in
the advanced
cou~t~~~
will do the trick. We need
therefore to say a bit about the modem deriva-
tions of this law.
Let us begin with a modern version of the
quantity theory, based on the cash balance ap-
proach. The classical quantity theory argued
that an outflow of gold from a country would
lead to a fall in the money supply and hence in
the price level. Here, it is argued that the de-
crease in the money supply implies a decrease in
the cash balances of individuals and firms;
in
order to “not let their cash balances shrink too
far,” people in the deficit country curtail their
consumption and investment spending, and this
drop in aggregate demand in turn leads to lower
prices and wages (Yeager, 1966,
p,
64). The op-
posite movement takes place in the surplus
country, and eventually absolute advantage
gives way to comparative.
An alternate path to this same result is made
possible by tying the price level to the level of
money wages. In this version, since the competi-
tion of cheap cloth and wine from abroad means
a reduction in dumestic wine and cloth produc-
The laws of international exchange 217
tion in the backward country, the resulting trade
deficit will be associated with a rise in un-
employment. Money wages in the backward
country will consequently fall, and with them
money prices; in the advanced country, the
trade surplus is associated with expanded em-
ployment, a rise in money wages, and hence a
rise in money prices. Even if money wages were
relatively sticky downwards, the above result
would hold since all that is required is a move-
ment in one of the two price levels so as to arrive
at the correct relative price levels. Once again,
this leads to the eventual rule of comparative ad-
vantage (Amin, 1974, p. 47).
All discussions so far have been predicated in
terms of the gold standard, in which the “ulti-
mate” basis of international currency is a money
commodity (which we call gold for conve-
nience). In most theoretical discussions, the
gold standard is treated as being equivalent to a
regime of fixed exchange rates. The preceding
modern derivations of comparative advantage
are therefore also presented as holding true for
the case of fixed exchange rates.
At the opposite theoretical extreme from fixed
exchange rates, we are told, lies the notion of
purely flexible exchange rates determined solely
by the relative supplies and demands of the na-
tional currencies. Here it is possible that each
nation will have a fully independent monetary
system (Yeager, 1966, p. 104). In this case, the
price levels in each country are “insulated”
from external influences, and all adjustments are
brought about through the exchange rate. In the
backward country the trade deficit will imply a
depreciation of the country’s currency, which
would make imports relatively more expensive
to it and its exports relatively cheaper abroad.
Since this process is assumed to have no limits,
eventually the flexible exchange rate would
settle at the level which made comparative ad-
vantage a reality.
We cannot consider the merits of these
various derivations until we have examined
Marx’s theory of money. But it is useful to note
even at this point that it is completely false to
equate the notion of the gold standard with fixed
exchange rates. As indicated at the end of this
chapter, note 20, in actual fact the gold standard
was a system of flexible exchange rates whose
movements were hounded by limits determined
by the costs of transporting gold. This meant
that insofar as the “normal” variations of trade
were concerned, the gold standard operated as if
it wcrc a system of purely flcxiblc cxchangc
rates. On the other hand, insofar as systematic
imbalances were concerned, the exchange rate
soon reached one of the two limits and it became
cheaper to settle debts by shipping gold directly:
in this mode, therefore, it operated like a system
of fixed exchange rates. The theoretical notion
of the two polar extremes of fixed versus flexible
exchange rates thus have their origin in one-
sided (and hence false) abstractions of the real
process. We will return to this important point
later on.
Marx’s development
exchange of the laws of capitalist
As the preceding discussion of Ricardo should
have made clear, it is the interaction of the Ri-
cardian theory of price with his theory of money
which results in the law of comparative costs.
Now, as we turn to Marx, we face the task of
trying to present, in a few short pages, the es-
sence of Marx’s theories of price and money so
that we may see what implications they in turn
have for international exchange. Here, the over-
riding question is whether the international ex-
tension of Marx’s law of value will indeed turn
out to be the law of comparative costs (as has
been generally assumed), or whether it will in
fact turn out to be something quite different.
Marx’s law of value has, of course, many
points of comparison with Ricardo’s analysis;
often, through an emphasis on these common
points, the impression is given that Marx was
therefore a (major or minor) post-Ricardian clas-
sical economist. Such an impression is, how-
ever: completely misleading and can arise only
through the
redtiction
of Marx’s analysis to only
those points which overlap with Ricardo’s. As
long as one begins with Ricardo as the home
base, all such comparisons are inevitably posed
in Ricardian terms; Marx thus emerges as the
cleverest Ricardian of them all.
Within the context of this brief exposition, it is
hardly possible to do justice to even the notions
of value and price in Marx, much less to the
methodological break between Marx and the
classical economists. Of necessity, many of the
points we seek to cover are precisely points of
comparison with Ricardo; nonetheless, the
reader must be forewarned that the differences
which do emerge are not merely variations on a
Ricardian theme. On the contrary, it is exactly
because Marx does not operate within a Ricar-
dian framework that he is able to go beyond Ri-
cardo’s own
analysis.22
Commodities. In the discussion of Ricardo’s law
of
prices,
the fundamental question seemed
fairly well defined: what are the laws of the
movements of prices of production?
What Ricardo perceives is that the “worth,”
the “exchangeable value,” or commodities
218 Anwar Shaikh
bears an intrinsic connection to labor-time
(Marx, 1969, pp. 164-7). This, says Marx, is Ri-
cardo’s greatest scientific merit (Marx, 1969,
p. 166). But at the same time, rather than devel-
oping the various intermediary links between
labor-time and price, Ricardo attempts instead
to fuse the two together in his law of prices. His
failure to adequately distinguish between labor-
time and price is, according to Marx. the first
great source of error in his analysis (Marx, 1969,
Ch. X; pp. 106, 164, 174-6).
In addition to that, however, there is another
problem. How can Ricardo attempt to analyze
the effects of a uniform rate of profit on prices,
asks Marx, when he nowhere discusses what de-
termines the level of this rate of profit? And this
in turn leads to an even more basic question. A
uniform rate of profit is simply a way of saying
that profits on different capitals are proportional
to the size of these capitals: that is, each capital
gets a share of total profit in proportion to its
own size. But Ricardo nowhere discusses what
determines the total profit in the first place. How
then can he attempt to isolate the factors which
regulate the movements of prices of production
when he is missing a crucial ingredient
-
profit?
It is apparent to Marx that before one can ar-
rive at the laws which govern price, one must
first answer two prior questinns: first, what is
meant by price and how does it arise? And sec-
ond, what is meant by profit, and how does it
arise?
Since the concept of price refers to the ex-
change of commodities, Marx begins by exam-
ining what a commodity is. In all societies, he
notes, human beings produce useful objects. It is
only in a particular type of society, however,
that the useful products of human labor are in-
tended not for some direct social use but for ex-
change. And precisely because exchange is a so-
cial process which quantitatively compares and
equates different products, in societies which
produce for exchange the products of human
labor acquire the property of having quantitative
worth. No longer are they merely useful; they
a~
ww
also valuable: they are commodities. As
Marx expresses it, a commodity is both a use-
value and an exchange value.
But when we say that a commodity is worth
something, just what is implied? Suppose I say
that in barter, a bushel of corn is worth a ton of
iron, and also a yard of silk, and an ounce of
gold, and so on. At first glance, what I appear to
be saying is that there are many different quanti-
tative expressions for the worth of a bushel of
corn, depending on which other commodity
(iron, silk, or gold) I choose to meusure it by.
But there is a deeper problem here. In order
for me to measure the worth of corn in terms of
gold, for instance, gold must also be worth
something itself. Otherwise I cannot say how
much gold is equivalent to a bushel of corn. It is
just like my saying that a stone weighs 10 grams;
what I mean is that on a scale it takes ten pieces
of iron called gram-weights to equal the weight
of the stone. But clearly, in order for me to carry
out this operation, both stone and iron must
already possess the property of being heavy, of
having weight; the gram-weights don’t make
stones heavy, they only measure the already ex-
isting heaviness of stones.
Exactly the same conclusion applies to quanti-
tative worth. The factors which cause conlmodi-
ties to have quantitative worth in the first place
must be carefully distinguished from the mea-
surement of this worth. Measuring the worth of
corn in iron will give a different result from mea-
suring it in gold; but neither measure causes
corn to possess quantitative worth. Rather, each
merely expresses the preexisting worth of corn
in terms of some particular commodity.
The question of price is therefore really a
two-fold one: first, what is the cause of quantita-
tive worth; and second, how is this worth actu-
ally expressed, measured, in exchange?
Value. If we look at society as a regularly repro-
duced set of social relations, it becomes very
clear that the production and reproduction of the
masses of useful objects which correspond to
various social needs requires a definite, quanti-
tative distribution of social labor. Each different
useful product requires a concretely different
type of labor; reproduction of the material basis
or
tlit:

r-txpirt;s
tlit:
ksl-
ence and reproduction of the appropriate quan-
tities of different concrete labors. That is to say,
social labor from the point of view of its capacity
to produce different use-values is what Marx
calls social-labor in its role as concrete labor
(Marx, 1967, Vol. I, p. 46).
We noted earlier, however, that in commod-
ity-producing societies each product, in addi-
tion to being useful, acquires the further prop-
erty of being valuable. Hence, labor which
produces commodities (i.e., objects intended for
exchange) itself acquires a new property:
namely, the capacity to create value or quantita-
tive worth. In this role, moreover, all com-
modity-producing labor is qualitatively alike,
since different types of labor differ only in
their resulting amounts of value. The very same
social conditions which make varied useful ob-
jects quantitatively comparable by reducing
them to a common denominator, also make the
corresponding labors quantitatively comparable.
In the case of the useful objects, their common
denominator is auantitative worth: in the case of
The laws of international exchange
219
the labors, it is the capacity to result in quantita-
tive worth. From the point of view of this latter
property social labor is qualitatively alike and
quantitatively comparable: it is what Marx calls
social labor in its capacity as abstract labor. Ab-
stract labor, that is, labor which is actually
engaged in commodity production, is the cause
of quantitative worth.
23
The total quantity of

or indirectly for the
production of a commodity Marx therefore calls
the intrinsic measure of its quantitative worth,
or its value.
The value of a commodity, the intrinsic mea-
sure of its exchange-value or worth, is the quan-
tity of abstract labor-time necessary for the pro-
duction of the commodity under average condi-
tions. If looms, for instance, are made in one
year by hand, and in a given year 100 looms are
produced, SO by
t;ffic;it;n
t p-oducers
rr=quiring
900 worker-hours per loom and 50 by inefficient
producers requiring 1,100 worker-hours per
loom, then the value of a loom in that year is
1,000 worker-hours. It is the average quantity of
labor-time necessary, not as in Ricardo, the
marginal, which counts here (Marx, 1967, Vol. I,
p. 39).
Suppose the production of a bolt of cloth took
10 workers ten hours a day for one week (six
days) to gather cotton seed, plant it, harvest
tilt:
cotton, and with the aid of a loom, spin the
cotton into cloth. Then the value of the cloth has
two components: the living labor of the cloth
worker, 600 worker-hours, which represents the
value added in cloth production during one
week; and that part of the value of the loom
which is transferred to the cloth. But how is the
latter to be determined? Well, if the loom was
used up in one week then it is clear that all the
value of the loom would be incorporated into the
cloth, since from a social point of view the
labor-time required to build the loom is the indi-
rect social cost of producing cloth. If the loom
lasted longer, say one year (50 weeks), then over
one year it will be entirely used up and all of its
value transferred to the
50
bolts of cloth pro-
duced in that period of time. On the average,
therefore, the loom would transfer
l/50
of its
value each year to a bolt of cloth. Because the
second case is basically the same as the first, we
will simplify the exposition from now on by
assuming a uniform period of turnover of one
week. Then the value of the cloth is 1,600
worker-hours: 1,000 of these trawferred by the
loom as it is used up, 600 added by living labor.
If we designate the total value of any output
produced in a given week as W, the value trans-
ferred by its means of production as C, and the
value added by living labor as L, then:
C+L=W
(13.3)
We turn now to the second aspect of price:
how is quantitative worth actually expressed in
exchange? To this Marx answers: in exchange,
the quantitative worth of a commodity
must
nec-
essarily take the form of money-price. Since ex-
change is the interchange of two commodities, at
first glance it seems obvious that there are as
many measures of a commodity’s worth as there
are other commodities to measure it by. And his-
torically, where exchange is sporadic or irregu-
lar, this is in fact true. But as exchange spreads
and develops, this variety of different possible
measures increasingly becomes a barrier to the
smooth functioning of the process; without a
point of reference, the direct comparison of
every commodity with every other becomes
impossibly complex. Consequently it becomes
increasingly necessary to settle on a given com-
modity out of all those available as the one com-
modity in which all other commodities express
their worth; this special commodity therefore
becomes the universal equivalent, the money-
commodity. We will henceforth assume it is
gold.
Notice that money does not by itself cause
commodities to have worth, any more than
gram-weights cause stones to have weight. On
the contrary, it is only because both gold and the
other commodities have
quantitative
worth
(exchange-value) in the first place that we can
express their worth in terms of gold. The
money-price of a commodity is the “golden” re-
flection, the external measure, of its exchange-
value. It is what Marx calls the
$5~~2
taken by
value during exchange (Marx, 1967, Vol. I, pp.
47-8).
Price. We have already seen that value, the in-
trinsic measure of exchange-value or quantita-
tive worth, and price, the external measure, are
two very different things. Money-price is the
manner in which the exchange process reflects
value. This in itself implies that all the relations
which intervene between the production of a
commodity and its actual sale can give rise to
further determinants of the precise form in
which this reflection will take place. For in-
stance, in general the market price of a commod-
ity is an expression not only of the amount of ab-
stract labor-time required for its production (its
value) but also of the distribution of social labor
-
that is, of the correspondence between the
amount of social labor devoted to the production
of a given commodity and the amount necessary
to supply the social need for this commodity.
if
at any moment this latter correspondence does
not hold, it will show up in the process of ex-
change as a discrepancy between supply and de-
mand;
t
,hen
even if on the average exchange i
s at
220 Anwar Shaikh
value it will not be so in this case. Market price
will deviate from natural price.
Marx himself points out this and other pos-
sible discrepancies between value and price
(Marx, 1972, pp. 61-2). But he notes, the only
way in which we can proceed to actually deter-
mine any quantitative differences between value
and price is to first proceed on the assumption
that price directly reflects value
-
that is, that
supply and demand are balanced (so that market
prices equal regulating prices, or natural prices)
and that the money-price of a commodity is its
value relative to the value of gold. In this way
we can identify the structural determinants of
the various steps in the movement from produc-
tion to exchange, and hence of the transition
from value to price. Only then can we show how
these structural determinants can in turn give
rise to more complex paths from value to price
(Marx, 1967, Vol. I, p. 166, footnote
1).24
Surplus-value and profit. We come now to the
second major criticism that Marx levels against
Ricardo: his inadequate treatment of profit.
Let us begin by recalling that it takes 1,000
worker-hours of abstract labor-time to produce a
loom by hand, and 600 additional worker-hours
to use this loom in producing cloth: C = 1,000,
L = 600, W =
1,600.
1000C
+
600L
=
1600W
= value of cloth (13.4)
But from the point of view of the capitalist,
the matter looks very different. To him, the
process starts with an investment of money M
and ends with the sale of the loom for. another
sum of money M’. The difference between the
two, AM =
M'
-
M, is that all important sum,
profit. How does this have anything to do with
labor-time, he asks?
Well, since exchange is in proportion to val-
ues, if the value of an ounce of gold is two
worker-hours, then the money-price of the cloth
must be 800 oz of gold. That gives us the end of
the circuit of capital:
M' = 800 oz
of gold.
What about the beginning? From the point of
view of the capitalists, the initial investment M
goes to buy the inputs of the process. One part
of
M,
which I will call
MC,
goes therefore to buy
a loom; since the value of a loom is 1,000
worker-hours, its price is 500 oz:
MC = 500 oz
of gold.
The other input is, of course, labor. But what
does it cost? Living labor, we have seen,
transfers the value of the loom to the value of the
product (cloth), and adds 600 worker-hours of
value in the process. If exchange is at values,
then the value-added by living labor is equiva-
lent to 300 oz of gold-money. Clearly, if the
labor input cost as much as 300 oz, then the cap-
italist’s cost would be equal to his price: there
would be no profit! For capitalist production to
be profitable, workers must accept as wages the
money equivalent of a value less than that
which they themselves add to the product. But
then, it would seem, exchange is no longer at
values !
This paradox was in fact a major source of
problems in classical political economy, and
Marx considered the solution to it one of his
great triumphs.
25
The way out, Marx shows,
lies in the distinction between labor-time and
labor-power. What workers sell in the market is
their capacity-for-labor, not their labor time.
The capitalist pays them a wage in return for the
right to set them to work each day; but how long
they work and how hard, how many hours of
average labor-time the capitalist actually gets
out of them, will depend on the struggle between
capital and labor. Quite apart from the wage rate,
the intensity of labor and the length of the work-
ing day have always been important battle
grounds in the class struggle. The capacity-to-
labor, what Marx calls labor-power, is therefore
very different from labor-time: it is the sum of
the mental and physical capabilities which a
worker can put to use in production, and as
such, its production and reproduction implies
that workers must receive as wages enough
money to buy their means of subsistence: food,
shelter, education, and training
-
in short, what-
ever is necessary to reproduce themselves as
workers. The value of labor-power, the social
labor-time required for the reproduction of
workers’ capabilities, is therefore the value of
their means of subsistence.
The paradox is now resolved. Workers enter
production as inputs having a specific value;
they leave production having added a quantity of
value to the product through their labor-time.
From the point of view of capitalist society,
therefore, profit can only arise if the abstract
labor-time socially necessary to sustain workers
(the value of their labor-power) is less than the
labor-time that they actually put in (the value
they add to production); in other words, if
workers produce surplus-value. Profit is the
money equivalent, the money form of appear-
ance of surplus-value. In the case of cloth pro-
duction, the value added by 10 workers in a
week is 600 worker-hours; if the value of their
labor-power was 400 worker-hours, the sur-
plus-value would be 200 worker-hours. Wages
would be 200 oz of gold so that profit AM =
M'
-
M = 800
-
(500 + 200) = 100 oz: profit
is the money equivalent of surplus-value.
We can summarize all this diagramatically.
Let V stand for the value of labor-power, and
Mv
for its money equivalent (the monev-capital

with which the capitalist purchases means

labor-power (10 workers) having value V; what
‘emerges from the process of production is a
product having value C +
L,
which then sells
for its money-equivalent
A4’.
The surplus-value
S
is thus reflected in its money-equivalent, the
profit AM.
Prices of production. We have up to now as-
sumed exchange in proportion to values, so that
we may isolate the intrinsic determinants of
price and profit. This is how Marx begins; but
then he immediately goes on to point out that in
general prices proportional to values would im-
ply different rates of profit in different sectors.
Figure 13.1 illustrates the problem. If all
money prices are proportional to values, then in
every sector the money investment 44 will be
proportional to the value cost C + V, and
noney profits M will be proportional to
surplus-value S. It follows from this that the
money rate of profit (AM/M) in each sector will
be equal to the corresponding value rate of
profit:
(AM/M) =
S/(C
+
V) =
&
(13.5)
The expression for the value rate of profit ob-
viously depends on the two ratios S/V and C/V.
We therefore need to
Jo,ok
at these
a
little more
closely.
Recall that surplus-value S is the excess of the
value added (L) by living labor over the value of
its labor-power. Now, if the wage rate is the
same for each worker (assuming that all labor is
of the same skill level
-
the issue of skill dif-
ferences is outside of the scope of this chapter),
then the value of labor-power is the same for
each; if in any given period each worker puts in
the same amount of labor-time as any other,
then
each adds the same value to the product.
Consequently, each worker produces the same
amount of surplus-value. It follows therefore
that in every sector the proportions of
L:
S: V
will be the same, though the respective size of
221
each will vary with the number of workers em-
ploy ed.
This has two immediate consequences for the
issue of profitability. First of all, the ratio S/V,
the rate
oj’
surp/~s-value, will be the same in
every sector. Second, since the proportion of
L
: V is the same in every sector, the ratio C/V,
the organic composition of capital, will in each
sector be proportional to the ratio
C/L.
So
whether or not C/V is, like S/V, the same in
each sector will depend on whether or not C/L is
the same.
The ratio
CfL
however, is in general not likely
to be uniform across sectors. It is the ratio of the
labor-time embodied in the means of production
to the living labor-time required to transform
these into the product; as such it reflects the
technical conditions of production in each
sector, and unless they are generally similar, it
will vary from sector to sector. This in turn
means that although the rate of surplus-value,
S/V, is iniform across sectors, in general the
organic composition,
C/17,
is not. From the cx-
pression for the rate of profit in equation 13.5
we can see that sectors with a high organic com-
position will have a low rate of profit, and vice
versa. It is an inescapable implication therefore,
that prices which are proportional to values will
in general embody unequal rates of profit.
When prices are proportional to values, profit
in any given sector is directly determined by the
surplus-value produced in that sector alone; but
then, as we have seen, rates of profit will differ
from sector to sector. It follows therefore that if
rates of profit are to be equalized, if high and low
rates of profit are to be made equal to the social
average, some sectors must get less profit, and
others more, than that indicated by their respec-
tive surplus-values. This can only come about if
prices of production deviate from direct prices in
a systematic way so as to redistribute the total
pool of surplus-value: in other words, in order
that the equal rates of surplus-value in various
sectors be realized in exchange as equal rates of
money profit, the sale of products must actually
take place at prices which differ systematically
from direct prices.
Clearly, what is involved here is
aschange,
a
transformation, in the form-ofivalue (money
price). But such a transformation can in no way
alter the total sum of values or the total pool of
surplus-value; the same products as before are
circulated, only now at different prices which
therefore entail a dBerent sharing out of the
pool of surplus value.
Marx deals with the transformation in the
form-of-value in a simple and powerful way. Ba-
sically, he points out that when exchange is
ruled
by
direct prices, sectors with hinher than
222
Anwar
Shaikh
average organic compositions C/V will have
lower than average rates of profit, and vice versa
(look at equation 13.5 to see why); from this
Marx concludes that in order for each sector’s
profit rate to be equal to the social average,
sectors with high organic compositions must
therefore sell their products at prices above their
respective direct prices, while sectors with low
organic compositions must sell at prices below
thei
r-espective
direct
prices.
What takes place
in the transformation from direct prices to prices
of production is a kind of rotation of prices, with
the average price as the (unchanged) center of
rotation. The total sum of prices is unaltered, as
is total profit; they remain directly proportional
to the total sum of values and the total
surplus-value respectively. Hence the average
rate is simply equal to the value rate of profit, as
in equation 13.5.
In his exposition, and in several other
places,
Marx notes the existence of what I call a feed-
back effect of the transformation just men-
tioned: since individual prices of production
differ from direct prices, this also means that
individual money investments, M, will in general
differ from the corresponding value costs C + V
(Marx, 1967, Vol. III, pp. 161, 164-5). Such a
feedback effect could make the relation between
value magnitudes and their price forms more
complex, Marx observes. But then he leaves this
issue aside, clearly because he considers it to be
of relatively minor importance in the process of
deriving price from value and profit from
surplus-value.
Marx’s opponents immediately seized upon
the incomplete nature of Marx’s transformation,
and, ever since then, this issue has been the
focus of a long-running debate. Recently this de-
bate has flared up once again, leading to some
important new results which support the essen-
tial nature of Marx’s derivations. It is entirely
beyond the scope of this chapter to go into this
matter in any depth; however, in a separate
paper (Shaikh, 1977) I do treat this connection in
detail. For our purposes here, three of its as-
pects are significant. First, that the procedure by
which Marx transforms direct prices can be also
viewed as the initial step in an iterative proce-
dure for
~crlculntin~
the actual prices of produc-
tion themselves. This helps establish a fruitful
mathematical connection between Marx’s pro-
cedure and further-developed prices of produc-
tion. Second, it can be shown (in the case of
three departments of production, at least) that
for each sector both the actual and the regulating
price of production deviate in the same direction
from the sector’s direct price, so too will be the
actual price of production. (Seton, 1957, pp.
157-60) Last, it has been established that the
transformed money rate of profit is directly re-
lated to the value rate of profit, though they
need not be equal in
magnitude.26
For most analyses, knowledge of the above
connections is generally sufficient. In this chap-
ter, therefore, I have used only direct prices
and Marx’s derivation of prices of production,
on the implicit understanding of the connection
between the latter and their further-developed
form.
The theory of money. We began the analysis of
price by noting that a commodity is a product of
human labor which is not just useful but also
valuable. This led us to examine the duality
implicit in the notion of quantitative worth,
which in turn led to the sharp distinction
between value, the intrinsic cause of quantita-
tive worth, and money-price, the measure or ex-
pression of this worth in terms of some universal
equivalent (gold). In order for commodities to be
equal in worth to some quantity of gold, that is,
in order for them to have money-prices, they
must already have worth: money does not cause
worth, it only measures it.
It is a necessary consequence that the factors
which determine how valuable a commodity will
be in exchange, determine its money-price. And
these factors, as we have seen, are the amount
and distribution of social labor-time
_
If the distribution of social labor is such that
the commodities produced correspond to the
various social needs, supply will equal demand,
and the money-price of a commodity will equal
its regulating price
-
direct prices if we assume
exchange in proportion to values
-
prices of pro-
duction at a higher level of analysis. In
either-
case, it is the amounts of labor-time which deter-
mine these regulating prices.
If, on the other hand, the distribution of labor
is not appropriate to various social needs, then
the market price of a commodity will deviate
from its regulating price, and a change will take
place in the distribution of social labor so as to
reduce the discrepancy between market and
regulating prices. For the purposes of this analy-
sis, therefore, we may leave out of consider-atiun
the constantly fluctuating market prices and
focus directly on regulating prices.
In any given year, the sum of prices of all the
commodities produced must equal the number
of coins in circulation times the velocity of circu-
lation. This, as Marx points out, is simply a
tuu-
tology.
In order to make it something more, we
must embed it in a theoretical structure.
Let us begin by assuming that the regulating
prices are direct prices. Then the price of any
commodity is its value relative to that of gold, so
that the sum of the prices of all the commodities
The laws of international exchange
223
produced in a given year is given by their total
value relative to the value of gold. Let TP stand
for the sum of prices, TW for the sum of values,
and U, for the value of a
mnit
(an ounce) of gold,
we can write
TP = (TW/o,)
(13.6)
In this equation, the sum of (regulating) prices
is the direct expression of the sum of values of
commodities. If the velocity of circulation is
k,
then the amount of gold, G (in the form of one-
ounce coins), which is required as a medium of
circulation is
G = TP/k = [(l/k)(TW/o,)]
(13.7)
The causation in this is very clear: the sum of
the values of the commodities produced in a
given period determines the sum of their money-
prices, and this in conjunction with the velocity
of circulation
,27
determines the number of (1 oz)
gold coins required for the circulation of the
commodities (Marx, 1967, Vol. I, p. 123, et
passim).
Though the preceding relations were derived
on the basis of direct prices, they are not the
least bit altered when we move on to prices of
production, for, as we have seen, the regulating
prices of production that Marx derives have the
same sum of prices as do direct prices. This
means that as far as the sum of the prices of all
commodities is concerned, the determination is
the same whether we assume direct prices or.
prices of production: the sum of prices equals
the sum of values divided by the value of an
ounce of gold. As a result, the quantity of gold
required is the same in either case.
What happens then if there exist more gold
coins than the required number? Well, the quan-
tity G is the number of gold coins which cir-
culate because they facilitate the circulation of
commodities. Therefore any quantity of coin
over and above this amount will be redundant in
circulation: it will at first take the form of idle
coin, excess coin (Marx, 1972, Ch. 2, Sec.
3a).28
But an excess supply of gold is a very different
thing from an excess supply of any other com-
modity. All other commodities, in order to fulfill
their function, must be sold, turned into gold
through the alchemy of exchange; but gold itself
does not have to be, in fact cannot be, sold. It is
money,
2g
the perfect and durable form of wealth
which all other commodities seek to obtain.
From the earliest stages of commodity produc-
tion, therefore, gold circulating in the form of
coin has existed side by side with noncirculating
gold in the form of reserve coin, in the form of
hoards, and in the form of luxury articles.
The very nature of commodity production, the
unceasing fluctuations of market prices and
quantities, requires that every commodity
owner have on hand a reserve of money to
accommodate day to day variations. Conse-
quently, the first manifestation of a persistent
excess of coin over the needs of circulation will
be the buildup of these reserves above the requi-
site levels; but then this superfluous gold, being
necessary neither for immediate circulation nor
for its anticipated variations, will be withdrawn
altogether from the vicinity of the sphere of ex-
change. It will either enter into hoards or it is
transformed into articles of luxury:
We have seen how, along with the continual
fluctuations in the extent and rapidity of the
circulation of commodities and in their prices,
the quantity of money current unceasingly
ebbs and flows. This mass must, therefore, be
capable of expansion and contraction. At one
time money must be attracted in order to act
as circulatmg coin, at another, circulating coin
must be repelled in order to act again as more
or less stagnant money. In order that the mass
of money, actually current, may constantly
saturate the absorbing power of the circula-
tion, it is necessary that the quantity of gold
and silver in a country be greater than the
quantity required to function as coin. This
condition is fulfilled by money taking the form
of hoards. (Marx, 1967, Vol. I, p. 134)
In countries where commodity production is
still primitive, hoards take the form of private
accumulations of gold scattered throughout the
country. But as commodity production, and
hence the banking system, develops and ex-
pands, hoards become concentrated in the res-
ervoirs of banks (Marx, 1972,
pp.
136-7). Under
these circumstances, excesses or deficiencies of
gold money relative to the needs of circulation
manifest themselves as increases or decreases of
bank reserves.3o
Hoards in the form of bank reserves, how-
ever, are very different from private hoards: to
the bank, an excess of bank reserves over the
legally required minimum is a supply of idle
bank-capital, money-capital which could be
earning profit for the bank but is instead lying
fallow. An increase in bank reserves is therefore
generally accompanied by a decrease in the rate
of interest as the banks strive to convert re-
serves into capital. Conversely, a drop in bank
reserves below the legal minimum tends to lead
to a rise in the rate of interest. Rather than
raising the price level, the immediate effect of an
excess of gold-money is to lower the rate of
interest: “If this export [of capital] is made in
the form of precious metal, it will exert a direct
Influence upon the money-market and with it
upon the interest rate . . .” (Marx, 1967, Vol.
TIT,
p. 577).

But now it might be asked: surely the fact that
the bank puts this extra money into circulation
via a lowering of the rate of interest also implies
that effective demand is thereby raised? And if
so, won’t this in turn imply that as a conse-
quence of this higher effective demand prices
will eventually rise
-
so that in the end the quan-
tity theory is right after all? Marx’s answer is
unequivocal: no.
We begin by noting that
an
increased supply
of gold can indeed lead to an increase in effec-
tive demand, either insofar as it is spent by its
original owners, or indirectly because it will ex-
pand bank reserves and hence the supply of
loanable money-capital, which will tend to drive
down interest rates, which may in turn increase
capitalist borrowing for investment.31 However,
even though this increase in effective demand
may temporarily increase prices of some com-
modities, and hence raise profits in some
sectors, it must eventually lead to an expansion
of production to meet the new demand. And as
production expands prices will fall until (all
other things being equal) they regain their origi-
nal levels. In this case the sum of prices of all
commodities will have increased, not because
the level of prices has increased, but because the
mass of commodities thrown into production has
itself increased. Thus, insofar as a pure increase
in the supply of gold
does
generate
an
increase in
effective demand (i.e., insofar as it does not sim-
ply expand bank reserves or go into the produc-
tion of luxury articles) it will also generate an in-
creased need for circulating gold coin.
It is important to note at this point that to
Marx, the notion of a capitalism that tends to be
more or less at full employment is a vulgar fan-
tasy. First of all, Marx notes that it is an inherent
tendency of capitalism to create and maintain a
relative surplus population of workers
-
the re-
serve army of the unemployed (Marx, 1967, Vol.
I, Ch. 25). Second, even with a given pattern of
fixed capital (plant and equipment), expansion of
production can easily be undertaken by ex-
tending and/or intensifying the working time in a
given working day (Marx, 1967, Vol. II, p. 258).
Last, it is an intrinsic requirement of
capilalisl
commodity production, which is regulated only
by the constant fluctuations of the circulation
process, to maintain stocks of various commodi-
ties so that the exigencies of circulation may be
met without disrupting the continuity of the pro-
duction process. It is precisely because of these
possibilities that the continuity of the production
process is possible alongside constantly varying
levels of production and sale. (Marx, 1973, pp.
X52-6)
It is extremely important to grasp this aspect
of circulating and fixated capital as speci$c
characteris tic forms of capital generally, since
a great many phenomena of the bourgeois
economy
-
the period of the economic
cycle, . . . the effect of new demand; even
the effect of new gold-and-silver producing
countries on general production
-
[would
otherwise] be incomprehensible. It is futile to
speak of the stimulus given by Australian gold
or a newly discovered market . . .
[ifi
it
were not in the nature of capital to be never
completely occupied . . . At the same time,
[note] the senseless contradictions into which
the economists stray
-
even Ricardo
-
when
they presuppose that capital is always fully
occupied . . .(Marx, 1973, p. 623)
Having located Marx’s criticism of Ricardo’s
theory of money,32 we can now turn to its impli-
cations for gold flows generated by changes in
the balance of international trade. In the case of
a surplus, for instance, there will be a net inflow
of gold into the country and a consequent in-
crease in the country’s supply of gold. Insofar as
this leads to an increase in effective demand,
production will expand, and with it the needs of
circulation. Part of the increased gold supply
will therefore go to meet the expanded require-
ments of circulation, part will pile up in bank re-
serves, and part will be absorbed in the ex-
panded production of luxury articles made of
gold. In addition, once we take international
trade into account, a part of the surplus gold
may be re-exported in the form of foreign loans
in search of interest rates, or as foreign invest-
ment in search of surplus-value. These last two
possibilities, as we shall see shortly, become im-
portant in a Marxian analysis of international ex-
hirgt;
.
In any case, Marx emphatically rejects the no-
tion that a “pure” increase in the supply of gold
will in general lead to an increase in prices:
It is indeed an old humbug that changes in the
existing quantity of gold in a particular
country must raise or lower commodity-prices
within this country by increasing or de-
creasing the quantity of the medium of circula-
tion. If gold is exported, then, according to the
Currency Theory, commodity-prices must
rise in the country importing this gold, and de-
crease in the country exporting it . . . But,
in fact, a decrease in the quantity of gold
raises only the interest rate, whereas an in-
crease in the quantity of gold lowers the inter-
est rate; and if not for the fact that the fluctua-
tions in the interest rate enter into the determi-
nation of cost-prices, or in the determination
of demand and supply, commodity-prices
would be wholly
unakctd
by t&m (Marx,
Capital, 1967, Vol. III, Ch. XXXIV, p. 551)
It should be noted at this point that Marx’s
The laws of international exchange
theory of money implies not only a rejection of
the Hume specie-flow mechanism on which Ri-
cardo’s
results were based, but also rejection of
the various modern versions (discussed in the
fourth part of the second major section) which
have replaced it.
The cash balance approach, for instance, re-
lied on a fall in effective demand in the backward
country to lead to a fall in money prices. But this
connection between effective demand and the
permanent level of prices is precisely what Marx
denies. Similarly, the price level of commodities
being determined by their value relative to that
of gold, the money wage cannot permanently
influence the price level: the Keynesian price
theory therefore will not work either.
That brings us back once again to the possibil-
ity of purely flexible exchange rates. As noted in
the fourth part of the second major section, the
actual gold standard operated with a flexible
e7c-
change rate bounded by limits (gold-points)
based on the costs of transporting gold. This
meant that in its normal variations it was a
system of flexible exchange rates, whereas in its
“limited” mode it operated as a fixed exchange
rate system.
It is out of this long experience that orthodox
theory falsely abstracted fixed and flexible ex-
change rates as two separate regimes. In this
context purely flexible exchange rates are pre-
sented as a mechanism whereby in theory a
world capitalist system can be made up of fully
“independent” national currencies (Yeager,
1966,
p.
104). As a theoretical possibility this
idea has always had an uneasy existence: the
history of currency “floats” strongly suggests
only a limited flexibility (Yeager, 1966, pp.
176-80),
and the history of the international
money system is very much a history of increas-
ing monetary integration, not separation. In a
sense, the notion of a purely flexible exchange
rate determined solely by supply and demand
considerations is one more manifestation of the
general neoclassical method in which all
“prices” are determined only by supply and de-
mand. In opposition to this, Marx’s method very

these
apparent variations: in the case of prices, these
arose from labor-times; in the case of exchange
rates, from the existence of the money commod-
ity (as in gold-points).
The law of value in international exchange
Perhaps the most fundamental result to emerge
from Marx’s criticism of Ricardo is
the
crucial
distinction between value and price. Money
mice. to Marx. is the external measure of the
225
value of a commodity. The very nature of com-
modity production requires not only that every
commodity be assessed in terms of some univer-
sal equivalent (hence the necessity of money),
but also that this assessment be contingent on a
series of factors, ranging from the vagaries of
supply and demand to the social limits imposed
by reproduction (hence the ultimate regulation
of market prices by value).
Marx’s analysis of the exchange of commodi-
ties within a nation is thus characteristically dis-
tinct from Ricardo’s. In what follows we shall
see that it is these very same differences which
necessarily imply an equally distinct Marxian
analysis of international exchange.
Comparative costs reexamined. We begin once
again with the familiar Ricardian tableau (Table
13.2). Portugal is absolutely more efficient in
both branches of production, and given the
value of
gold33
as two worker-hours per ounce,
this greater efficiency translates directly into an
absolute cost advantage. Portuguese capitalists
will therefore export both cloth and wine, and
England will have to counterbalance its ensuing
trade deficit by shipping gold to Portugal.
According to Ricardo, the gold outflow from
England would lower all prices there, since it
would lower the domestic supply of money; con-
versely, the gold inflow into Portugal would raise
the prices of all Portuguese commodities. As we
have seen, this process implies that sooner or
later English cloth would undersell its Por-
tuguese counterpart, so that in the end two-way
trade would always reign. No nation need fear
trade, for it benefits all.
But the mechanism which leads us to this har-
monious conclusion rests squarely upon the
operation of the classical quantity theory of
money, And this we know to be false. Let us
therefore begin again.
Because of their absolute advantage, Por-
tuguese capitalists in both branches are able to
undersell their English competition. Portuguese
cloth and wine invade English markets, and
English gold begins to flow back to Portugal. In
England, therefore, the supply of gold de-
creases, while in Portugal it increases.
It is at this point that Marx’s theory of money
becomes critical. In contrast to Ricardo, Marx

expressly denies any link between pure changes
in the supply of gold and the level or prices.
Instead, according to Marx’s analysis, the pri-
mary effect of an outflow of gold from England
will be to diminish the supply of loanable
money-capital. On the other hand, as English
cloth and wine production succumbs to foreign
competition, the demand for money-capital will
also decrease. Nonetheless, when these sectors
have reached their minimal size (there will
always be Englishmen who will never buy from
foreigners), the continuing drain of gold will tend
to raise the rate of interest; insofar as this cur-
tails investment, production of other commodi-
ties will decline. In England therefore, the drain
of bullion will lead to lower bank reserves, cur-
tailed production, and a higher rate of interest.
In Portugal, the effects are just the opposite.
As gold flows into Portugal, part of it will be ab-
sorbed by the expanded circulation require-
ments of cloth and wine production; part will be
absorbed in the form of luxury articles; and the
rest will be absorbed in the form of expanded
bank reserves. This last effect will increase the
supply of loanable money-capital, lowering
interest rates and tending to expand production
in geneI-al. Thus, in Pmtugal, the inflow uf gvld
will raise bank reserves, expand production, and
lower the rate of interest.
What we find therefore is that according to
Marx’s analysis England’s absolute disadvan-
tage will be manifested in a chronic trade deficit,
bulanced by a persistent outflow of gold. On the
other hand, Portugal’s greater efficiency in pro-
duction will manifest itself in a chronic trade
surplus, balanced by a persistent accumulation
Obviously such a situation cannot continue
indefinitely.
34
If we stick to commodity flows
alone, then as English bank reserves decline, so
too will the credibility of the English
2;
eventu-
ally, the
&
must collapse, and with it the trade
between England and Portugal.
The end need not come in such a straightfor-
ward manner, however. We noted earlier that as
English reserves shrink, the rate of interest in
England will rise; conversely, as money-capital
piles up in Portugal, the rate of interest there will
fall. At some point, therefore, it will be to the ad-
vantage of Portuguese capitalists to lend their
money-capital abroad, in England, rather than at
home. When this happens, short-term financial
capital will flow from Portugal to
England;35
England’s rate of interest would then reverse it-
self and begin to fall, while Portugal’s would
rise, until at some level of short-term capital
flows the two would be equal.
It may seem that at this point the s
would be balanced: England running aituation
chronic
trade deficit which it covers by means of
short-
term international borrowing, and Portugal run-
ning a trade surplus which enables its capitalists
to engage in international lending. But of course
this is not quite correct: capitalist loans are
made in order to get profit (in the form of inter-
est). Thus England would have to eventually pay
back not only the original loan, but also the
interest on it. The net effect must be an
outJEow
of gold from England, albeit at a later date. All
other things being
equal,36
the piper must be
paid: in the end, beset by chronic trade deficits
and mounting debts, England must eventually
succumb.
The foregoing results take on an unpleasantly
familiar ring when we express them in terms of
developed and underdeveloped capitalist coun-
tries. Curiously enough, in Ricardo’s example
England corresponds to the under-developed
capitalist country (UCC), its generally lower ef-
ficiency being the reflection of its lower level of
development. Portugal, on the other hand, cor-
responds to the developed capitalist country
(DCC).
Cast in these terms, we may say: in free trade,
the absolute

veloped
ccrpitulist
country will

in chronic
trade dejkits und mounting international bor-
rowing. It will be chronically in deficit und
chron-
icully
in debt.
In our analysis so far, we have assumed only
two commodities, so that an absolute advantage
implies greater efficiency in producing both: oth-
erwise it would obviously be a relative advan-
tage. But when we consider the whole range of
products possible in both countries, then it be-
comes evident lhat in
spik
of a gm~-uZ supcl.iur-
ity in production, the DCC may nonetheless pro-
duce certain commodities at a greater cost than
the UCC, and yet others not at all. Since we are
still considering direct prices, the only possible
exports of the underdeveloped country will con-
form precisely to these types: commodities it
can produce at a lower value and/or those com-
modities peculiar to it
only.37
On the whole,
these types of commodities will reflect some
specific local advantages great enough to over-
come the UCC’s generally lower level of effi-
ciency: a good climate, an abundance of particu-
lar natural resources, a propitious location, and
so on; lower wages, however, will not matter
here, since in the case of direct prices the level
of wages affects profits but has no effect on
prices. Under these circumstances, then, the
underdeveloped country will be able to eke out a
few exports; although, of course, its overall
trade will still be in deficit, and its position still
that of a debtor nation. Trade will serve not to
eliminate inequality, but to perpetuate it.
The laws oj’international exchunge
227
This result is’not substantially modified by the
consideration of prices of production. Since
within a given country the average price of pro-
duction is equal to the average direct price, the
overall advantage of the DCC remains un-
changed. What may change, however, are the
trading positions of individual sectors. Within
each country, sectors with high organic compo-
sitions will have prices of production above their
direct prices, and sectors with low composi-
tions, prices of production below their direct
prices; but this dispersion
effGct
holds true in
both countries, to differing degrees, so that it is
quite possible that in either country some pre-
viously marginal sectors may enter international
competition while others drop out.
What we are left with, therefore, is that in gen-
eral the developed capitalist country will domi-
nate trade because its greater efficiency will
enable it to produce most commodities at abso-
lutely lower values, and hence, to sell them on
the average at absolutely lower prices of produc-
tion.
Above all, it must be kept in mind that these
results represent the automatic tendencies of
free and
unhumpered
trade among capitalist na-
tions at different levels of development. It is not
monopoly or conspiracy upon which uneven
development rests, but free competition itself:
free trade is as much a mechanism for the con-
centration and centralization of international
capital as free exchange within a capitalist na-
tion is for the concentration and centralization of
domestic capital. We will return to this point
after we consider the effects of direct invest-
ment
_
Incidentally, it is worth remarking that trade
between capitalist nations with more or less the
same level of development will have a character-
istically different pattern. Suppose we consider
the example lying at the heart of the Hecksher-
Ohlin-Samuelson model, in which both capitalist
countries possess the same technology and level
of productivity
-
so that absolute advantage is
impossible. In this limiting case, factors such as
climate, location, avail;lbility of resources,
experience, inventions, and above all the com-
petitive struggle among capitalists, become all
important. We would expect a more or less bal-
anced pattern of trade in this case, with a large
variety of goods being produced in both coun-
tries, and with the advantage in particular com-
modities shifting back and forth in the short-run.
This is quite different from the structural imbal-
ance of DCC-UCC trade.
The effects of direct investment. It is traditional in
the analysis of international trade to separate
commodity flows from
flows
of capital (direct in-
vestment). The law of comparative costs is then
used to justify the patterns of commodity trade,
while direct investment is treated (separately) as
a transfer of savings from the rich capitalist na-
tions to their poor relatives.3s The underde-
veloped capitalist nations thus emerge as doubly
blessed: the overwhelming productive superior-
ity of the developed nations is manifested only in
the cheapness of their exports, while their
incumyarably
greater wealth manifests itself as a
mass of capital eager and willing to go over there
and help spread freedom, equality, property,
and Coca-Cola.
The preceding section has demonstrated that
the law of comparative costs is invalid even on
its
owy2
groutids.
The concentration and central-
ization which is inherent in capitalist production
is as much a part of world capitalism as it is of
any single national entity; no form of exchange,
be it national
or
inturliztiunal,
can do more than
to give vent to the fundamental laws of capitalist
production. Rather than negating the inequality
of development, commodity trade affirms and
reinforces it.
But then what are we to make of the existing
analyses of the effects of direct investment?
On one hand, orthodox economic analysis
argues that direct investment “redistributes
world savings’ ‘I(Kenen, 1968, p. 29) from the
rich capitalist
nalions
tu
the
yuu~-
ones, which
tends to eliminate international inequality by
slowing down the growth of the investing coun-
tries and speeding up the growth of the recipient
countries. As such, might it not offset the
inequality-widening effects of commodity trade?
On the other hand, as I outlined earlier, both
conventional Marxist analysis and that of Em-
manuel rely heavily on the export of capital as
being the critical factor in modern imperialism.
But both analyses are based on an explicit
acceptance of comparative (instead of absolute)
advantage, a law which we now know to be
incorrect. To what extent, therefore, does the
overthrow of this law also modify either or both
of the above theories of imperialism?
These issues lead us directly to the central
question of this section: how does the consider-
ation of direct investment modify the previously
derived law of international exchange? In order
to answer this, we begin by developing the de-
terminants of foreign investment.
Let us recall the results of merchant capital
(i.e., commodity) flows: on the average, the
absolutely greater productive efficiency of the
DCC translates into lower international prices
for its products. If we consider products whose
consumption is common to
both,3g

advantages such as climate, availability of
resources, etc.
are
so great as to offset their gen-
erally lower efficiency.
We must keep in mind the elements of this re-
Iationship. The
DCCJ
has the advantage precisely
because it has a more developed structure of
pruduction, two aspects of which are of impor-
tance here: first, a superior technology; and sec-
ond, a work-force more conditioned to capitalist
production. The
UCC,
on the other hand, has an
inferior technology and a work-force which is
still new to wage-labor. The greater efficiency of
production in the DCC is therefore due partly to
the superior technology, and partly to the higher
direct productivity of its work-force. The term,
“direct productivity,” refers to the fact that
even when both work-furces use the same tech-
nology, the work-force of the DCC is likely to be
able to produce more output, because of its
greater conditioning to capitalist production, its
greater familiarity with machines, etc.
On the basis of these differences, then,
merchant-capital will facilitate trade between
the two countries in those commodities which
are of use
Jn
either country.
3ut
note that so long
as the differences in development manifest
themselves in the above-stated ways, the means
of production of the two countries will not be
among the traded commodities: each country’s
capitalists will use means of production consist-
ent with its general level of development.
Merchant capital necessarily carries with it
the possibility
o-F
modernization, however: the
capitalists within the UCC may (and do) switch
over to the superior technology of the DCC. But
there are many factors which militate against
this: the vastly greater cost and scale of ad-
vanced techniques, the complex interdepen-
dence required among different techniques for
any one to be viable, and the greater socializa-
tion required of the work-force. For these
reasons, modernization from the inside as an
inherent tendency of trade relations is usually
overwhelmed by another more powerful inher-
ent tendency: nodenzizaGon from the outside,
or direct investment.40
Precisely those factors
which
work against
modernization from the inside tend to work in
favor of direct investment: capitalists from the
DCC have much larger capitals available for in-
vestment, are familiar with modern techniques,
have access to all the necessary skilled workers.
But the most important factor which favors
direct investment, as we shall see, is the low
level of wages in the UCC.
During the analysis of commndity trade, wage
differences did not appear to be an important
factor. In the case of direct prices, price is deter-
mined immediately by value: wages affect only
the rates of profit. In the case of prices of pro-
duction, because the wage rate affects the
average rate of profit, it can affect the extent to
which individual prices of production deviate
from direct prices; but the average price is still
directly connected to value. Up to this point,
therefore, it has been necessary to focus on
dif-
ferences in productive efficiency as the most im-
portant manifestations of uneven development,
even though differences in wage rates between
DCC and UCC are just as symptumatic of the
disparity between their levels of development,
Once we admit the possibility of internationai
movements of industrial capital, however, wage
disparities between capitalist nations become an
important factor in their own right.
Consider the case of an individual capital in
the DCC. If we ignore transportation costs, then
the same price rules everywhere. Thus, it

tries will therefore arise from the differing costs
of labor-power; that

from the combined
ef-
fects
of the differences in direct productivity and
the differences in wage rates.
In Uneylrul Exchunge . . . , Arghiri Em-
manuel points out that though the direct produc-
tivity of labor is generally lower in the UCC,
tlze
wage rate is much lower still: whereas the direct
productivity “of the average worker in
tlze
underdeveloped areas is
50
to 60 percent of
that
of the average worker in the industrialized
areas . . . the average wage in the developed
countries is about 30 times the average wage in
the backward countries” (Emmanuel, 1972,
p.
48). This means that although it takes roughly
twice as many workers in the UCC to produce
the same output from a given plant

at home, each worker costs the developed
country’s capitalist only I/30 of what workers
cost at home; the net effect is that the average
wage bill of a plant located in the UCC would be

that cheap
labor is not the only source of attraction
for
foreign investment. Other things being equal,
cheap raw materials, a good climate, and a good
location (if transportation costs are taken into
account) are also important in making individual
sectors of production attractive to foreign capi-
tal. But these factors are specific to certain
branches only; cheap wage-labor, on the other
hand, is a general social characteristic of under-
develcqwd
capitalist crrtlntries,
one
whnse
impli-
cations extend to all areas of production, even
those yet to be created.
One immediate consequence of considering
The laws of international exchange
direct investment is that the export industries of
the UCC emerge as the prime targets of foreign
capital. As we have already seen, when we treat
flows of merchant capital, the only sectors of the
UCC capable of surviving are those whose prod-
ucts have no foreign counterparts, so that they
face no competition from imports, and those
which do face foreign competition but can over-
come it due to local advantages such as plentiful
raw materials, etc., which enable them to offset
their generally inferior technology and lower
labor productivity. The latter group of sectors, if
they exist at all, become the export sectors of
the UCC. And once the possibility of foreign in-
vestment is taken into account, these export
sectors become leading candidates for foreign
takeover: even if foreign capitalists had to ship
over workers from their own country their supe-
rior technology would still enable them to take
advantage of the cheap raw materials, etc., to
make exceptional profits; in addition, since labor
in the UCC is available at a lower net
cost,41
the
export sectors begin to appear even more attrac-
tive to foreign investors.
The sectors confined solely to domestic pro-
duction are not exempt from this process, how-
ever. Insofar as there exist within this group cer-
tain industries in which the superior technology
of foreign capital and the lower net cost of do-
mestic labor power enables the capitalists from
the DCC to make higher profits there than they
would at home, these industries too will be prey
to the foreign invasion.
In all the sectors subject to this discipline,
foreign capital enters because by selling at or
even below the existing prices, it can enjoy a
higher rate of profit than the rate which rules at
home. The existing prices, however, are the
prices of production of these sectors, embodying
the average rate of profit in the UCC. At first
glance therefore, it would seem that direct in-
vestment would only flow from the DCC to the
UCC if the former’s average rate of profit was
higher than the latter’s
-
because of the lower
wage, for instance, in the UCC. But this is not
necessnq~ nt
n/Z.
By modernizing from the out-
side, foreign capital lowers the cost-price of a
commodity and so raises its profitability. Thus
even if the national rate of profit in the UCC
were below that of the DCC, the sectors moder-
nized by foreign capital could still yield for it a
higher rate than either national
average.42
Regardless of the actual differences in the
average rates of profit of the two countries,
therefore, foreign capital will seek to enter those
particular industries in which it can enjoy a
higher profit (at the going prices) than it would
at home. As it does so, however, the competi-
tion among foreign canitals for these excess
229
profits will lead to an increase in the supply of
the commodities produced, driving down their
prices and hence reducing the excess profits
which attracted them in the first place. No
matter where this process stops, it is clear that it
will end up lowering the prices of the chosen in-
dustries until the foreign capital invested in them
earns the same rate of profit as it would at home.
From the point of view of local capital the ef-
fects of foreign investment will generally be
disastrous. The prices which existed before the
modernization from the outside were prices of
production embodying the average rate of profit
in the UCC. When these prices are driven down
by the influx of foreign capital, the domestic cap-
italists will be forced out
-
out of business, into
yet unaffected areas or into new industries
created in response to the needs of the foreign
dominated sectors.
We have up to now confined ourselves to ana-
lyzing the effects of direct investment on indus-
tries already existing in the UCC. Given that
only a few industries would survive the rigors of
commodity trade, the question that arose was:
will direct investment help offset the devastation
of competition from foreign imports, or will it
make matters worse?
From the point of view of local capital, the
answer seems unambiguous: worse! Struggling
to exploit their workers in peace, they find them-
selves beset by foreign devils: first their indus-
tries are ruined by cheap imports, and then those
that survive are taken over by foreign capital! It
is no wonder that protectionism becomes their
religion.
The invasion and takeover of existing indus-
tries in the UCC does not, however, exhaust the
possibilities inherent in direct investment. It
must be remembered that all capitals compete
against each other. This means that when capital
from the DCC takes the form of foreign invest-
ment it competes not only with capital from the
UCC but also with capital still at home. Where it
can take advantage of the cheap labor in the
UCC, new capital in the DCC can set itself up in
oppositiorz
to existing
hor72~
irduslries,
by
opening plants abroad and exporting the
(cheaper) products.
We see, therefore, that attraction of cheap
labor for foreign capital can be detrimental not
only to local capitals in the UCC but also to cer-
tain capitals in the DCC. It is for this reason that
the cry for protectionism resounds on both sides
of the development gap. Where merchant capital
dominates, or where foreign investment is still
no threat to home capital, then only the plaintive
wail of UCC capitalists is heard in favor of pro-
tectionism. But when foreign investment
develops to the point of competing with home
230 Anwar Shaikh
production itself, the protection quickly be-
comes the reality of the day. Only the free
traders remain, tirelessly selling the patent medi-
cine of comparative costs.
From a nationalist point of view, the effects of
direct investment on the UCC seem mixed. We
have seen that merchant trade will be dominated
by the DCC; the UCC will emerge as perpetually
in debt and perpetually in deficit.
Insofar as foreign capital invades the sur-
viving industries, it adds insult to injury by
increasing the dependence of the UCC on the
developed capitalist world. Direct investment, it
is true, does lower prices and modernize in-
dustry; but, as Emmanuel emphasizes, lowered
prices of exports are actually a loss to the
nation-as-a-whole, since they constitute a deteri-
oration of the terms of trade and hence a worsen-
ing of the trade balance. Moreover, for Em-
manuel the important point would be that both
modernization and the lowered prices are in fact
mechanisms by which the surplus-value pro-
duced by workers from the UCC is in fact trans-
ferred to the foreign capitalists. This, he argues,
further widens the gap between developed and
underdeveloped countries; by strengthening the
rich and weakening the poor: “wealth begets
wealth . . . Poverty begets poverty” (Em-
manuel, 1972, p. 131).
What Emmanuel does not see, however, is
that foreign investment may also transplant in-
dustries from the DCC to the UCC, because of
the advantages of cheap labor. lnsofar as this
happens, the export capability of the UCC is
strengthened (albeit under the aegis of foreign
capital) by the addition of these new sectors.
This side of foreign investment will tend to im-
prove the underdeveloped nation’s balance of
trade, and create new avenues of employment
for its labor.
The fundamental error in Emmanuel’s analy-
sis, however, is much more basic: because he
accepts the law of comparative costs as being
correct on its own grounds, he is forced to put
the whole blame for international inequality on
the effects of direct investment. Since he iden-
tifies the lower wages of the UCC as the basic
factor leading to foreign investment, Emmanuel
must argue that the sollrtion to the problem of
uneven development is to eyuulize wuges he-
tween countries. By so doing, the flow of
industrial capital from the DCC to the UCC
would cease, and with it all the deleterious ef-
fects which arise from it.
But we know that in fact Ricardo’s law of
comparative costs is wrong: quite independently
of direct investment, commodity trade by itself
will result in the penury of the underdeveloped
capitalist country. If anything, direct investment
can be an “offset” of a sort, albeit one which
eventually intensifies the unevenness of devel-
opment: inflows of foreign capital, even though
they may be eventually repaid many times over
in outflows of profit, are nonetheless an impor-
tant source of long-term borrowing to offset the
chronic trade deficits, ones which are generally
preferable to the volatile financial capital flows
upon which short-term borrowing is based,
Moreover, as noted above, direct investment
can lead to the creation of new industries in the
UCC, which can help reduce its trade deficit as
well as increase employment within the country.
The basic point, which Emmanuel’s proposed
solution completely misses, is that you are
damned if you do, and damned if you don’t.
What Emmanuel sees as an inequality between
nations is in fact the international manifestation
of the inequality between capitals which is inher-
ent in the necesstrvily uneven development of
capitalist relations of production. Concentration
and centralization as inherent tendencies of cap-
italist development are just as valid internation-
ally as they are nationally. In either case, the
patterns of exchange are symptoms, not causes,
of these fundamental laws, The international
equalization of wage rates can no more solve the
problem of uneven development in capitalism
than can the suppression of a symptom cure the
disease. The problem lies with capitalism, not its
symptoms: to argue for the same wage every-
where is in reality to argue that the exploitation
of workers should be equal in all
countries43
-
without reference to race, color, creed, or na-
tional origin! Democratic, no doubt, but limited
in its implications.
Summary and conclusions
The purpose of this chapter has been to work
towards the treatment of the laws of interna-
tional exchange from the Marxist perspective.
This is a theoretical task, one which has its roots
in the law of value as it is developed in the
SUC-
cessive volumes of Capital. As such, this analy-
sis is not a substitute for the concrete reality of
international trade or of its historical develop-
ment. No attempt is made, for instance, to
explain the historical roots of uneven devel-
opment
;
nor is primitive accumulation ever
treated. Instead, the point is to uncover the sorts
of forces which are inherent in the international
interactions of capitalist nations precisely so
that we may be better- prepared to

concrete existence.
Perhaps the most enduring proposition in the
The laws of international exchange
analysis of international trade has been the
so-
called law of comparative costs, which, as we
have seen, has generally been accepted by
orthodox economists and Marxists alike as being
valid on its own grounds. In all of its various
disguises, this so-called law has asserted that
when it came to international trade between cap-
italist nations, inherent inequalities will be
negated. Thus even if one of two nations cmld
only produce all commodities at a higher price
than the other, it would nonetheless end up ex-
porting some and importing others. No nation,
however humble, need ever fear “free trade,”
for, like bourgeois justice, it is blind to dif-
ferences in station. Or so the story goes, any-
way,
But it turns out that aside from the multitude
of proofs about the “optimality” of specializa-
tion according to comparative costs, the real
heart of the matter lies in the assertion that the
basic thrust of international trade is to actually
bring about such specialization. And the auto-
matic mechanism which supposedly accom-
plishes this, we found, was the operation of the
various orthodox theories of money.
The second part of this chapter therefore pre-
sented the development of the principle of com-
parative costs in its original (and basically unal-
tered) form: that of David Ricardo. Only then
were modern derivations of this law presented.
It was important in this section to show that the
so-called law was a logical outcome of the con-
junction of Ricardo’s theory of value with his
theory of money; this enabled us to establish
that the locus of a critique of the law lay in its
antecedents
-
not in the law itself.
In his analysis of Ricardo, Marx provides us
precisely with the necessary critiques of Ri-
cardo’s theories of value and money. Moreover,
in his own work he treats these subjects under
the developments of the law of value. The third
section of this chapter presented Marx’s critique
ofRicardo as well as his own treatment of value,
price and money. This has a double conse-
quence: the critiques of these antecedents of the
su-called law of comparative costs provides us
with a basis for a critique of the law itself; and
Marx’s own development of the law of value
provides us with the basis for an adequate treat-
ment of the laws of international exchange. And
when this is done the law of comparative costs is
seen to be impossible precisely on its own
grounds. Rather than finding, as Ricardo did,
that Portugal and England will each end up spe-
cializing in one commodity
-
in spite of Por-
tugal’s absolure superiority in the production of
both
-
we find that Portugal will necessarily ex-
port both. England. the
underdevehed
capital-
231
ist country in this example, will end up with a
persistent trade deficit balanced by gold out-
flows and/or short-term borrowing.
When this result is expressed in terms of its
real content, we can say: free trade will ensure
that the underdeveloped capitalist country will
be chronically in deficit and chronically in debt.
It is ahsolute advantage, not comparative, which
rules trade.
This result represents the extension of Marx’s
law of value (which in Marx subsumes a theory
of money) to the realm of the international ex-
change of commodities. But as Marx points out,
these commodities are capitalistically produced
commodities, the commodity-form of various
national capitals. As such, the interchange of
commodity-capitals among nations carries with
it the seeds of other forms of international capi-
tal,
such as financial capital (foreign bor-
rowing/lending), and direct investment.
The question of direct investment is particu-
larly important, since its analysis plays so im-
portant a role in various theories of trade. Ortho-
dox theory, for instance, finds direct investment
to be a means of closing the gap between rich
and poor capitalist countries, on the grounds
that it transfers savings from the developed
countries to the underdeveloped ones. Marxist
theories of imperialism, on the other hand, have
traditionally derived the major phenomena of
uneven development from direct investment; in
this regard Emmanuel, too, makes the export of
capital pivotal in his theory of imperialism.
But all these analyses of direct investment are
based on an acceptance of Ricardo’s law of com-
parative costs. Since the central result of this
paper is the overthrow of this law, and the sub-
sequent location of many of the phenomena of
imperialism
-
previously attributed to the export
of capital
-
in the workings of commodity trade
alone, it became imperative at that point to ex-
tend the analysis to incorporate the effects of
direct investment.44
In the second part of this chapter’s final sec-
tion, this question was taken up. There, it was
found that though foreign capital can provide an
offset to chronic balance of trade deficits, in part
because of the capital inflow and in part through
the modernization and expansion of the export
sectors, it does so only at the expense of an
eventual capital outflow (surplus-value trans-
ferred out in the form of repatriated profits), de-
clining terms of trade, and increased foreign
domination. Instead of negating international
inequality, therefore, foreign investment tight-
ens the grip of the strong over the weak

7 Properly speaking, neo-Keynesian analysis seeks
to trace the short-run consequences of changes in
patterns of trade, rather than attempting to specify
the actual determinants of trade. It is therefore
often presented as a complemerzt to the law of com-
parative costs.

“trade union action,” and the inequal-

underdeveloped capitalist countries, for the his-
torical inapplicability of free trade arguments
(Bar-rat-Brown, 1974, pp. 32, 35, 38, 233).
9 It might be added that a satisfactory resolution of
the problem of price formation in competitive capi-
talism (the so-called transformation problem) may
well point the way to a better treatment of monop-
oly. An inadequate
undtxstanding
of the former
would almost surely hinder the development of a
satisfactory understanding of the latter.
10 “The behavior of labor remains a matter of indif-
ference for the application of the law of compara-
tive advantage, the sole condition, both necessary
and sufficient, for this proposition being the mobil-
ity of capital” (Emmanuel, 1972, pp. xxxi-ii).
11 Emmanuel does not abandon the law of compara-
tive costs, even for the modern world. Rather, he
sees the modern law to be the sum of two pro-
cesses; first, the formation of international
prices
of production via international equalization of the
rate of profit; and second, specialization according
to comparative costs, where comparative cost
ratios are determined precisely by the international
prices of production. In Chapter 6 of

change . . . , he illustrates the effects of unequal
exchange on the pattern of specialization. assum-
ing throughout that this pattern is based ultimately
on comparative costs.
12 The term Third World is used occasionally
throughout this chapter in deference to its wide-
spread popularity. It is, however, a very mislead-
ing term in that it suggests a separation between the
poor capitalist countries and world capitalism.
13 Emmanuel particularly emphasizes stagnation,
poverty, a widening “development gap,” and de-
clining terms of trade for Third World countries
(Emmanuel, 1972).
14 It is clear from Emmanuel’s analysis that capital-
ists are free to use the best technique of production
available. On page 6
1
he refers to the example of
page 63, which assume the same technology in both
countries (Emmanuel, 1972).
15 Emmanuel’s analysis tends to be posed in terms of
nations as the primary units, not classes.
16 It is worth remembering that Proudhon’s philoso-
phy of poverty also depends on a notion of equal
exchange.
17 It is interesting to note that Marx’s reaction to
Ri-
cardo,
for example, is critical, appreciative, and
nonpolemic. This is different from Marxist critics
of Emmanuel (who might rightly be called a
neo-
Ricardian).
18 The natural prices of Ricardo and the prices of pro-
duction of Marx currently go by a variety of names,
the most common being “long-run equilibrium”
prices. We will stick to Marx’s terminology here.
19 Adam Smith of course postulated a
precapitalist
law of prices in which relative prices
equalled
rela-
tive labor-times. In that sense, one could claim that
Smith dealt with a case in which there were no cap-
italists. But this has nothing to do with ignoring
means of production, which is what neoclassical
asxrtiurls
abuut
Ricardo and Smith amount to.
20 In fact, the gold standard operated with exchange
rates which could vary within certain limits. These
limits, called gold-points, determined whether it
was cheaper to change local currency into foreign
currency via the exchange-rate, or to buy gold with
the local currency and spend the gold abroad. The
basic determinant of the gold-points was the cost of
transporting gold-bullion from one country to an-
other.
21 In neoclassical presentations, the comparison is
between price ratios of cloth and wine in each
country, rather than efficiency of production. But
the conclusion is the same.
22 Althusser discusses the methodological break
between Marx and the classical economists
(Alt-
husser, 1970).
23 The distinction between concrete labor and ab-
stract labor is related to (though different from) the
distinction between productive and unproductive
labor. In both cases the properties of value (and
surplus value) producing labor are at the heart of
the distinction.
24 The case of rent is a good example of this method.
Land is not a product of human labor and conse-
quently has no value; yet land has a price. A clear
contradiction in Marx’s theory of value, it would
seem. Not at all, Marx replies. One of the neces-
sary steps in the theoretical transition from value to
price is the formulation of the concept of rent.
Once it is understood how value determines rent,
and it is seen that the price of land is nothing but
rent capitalized (percent-discounted) into a sum of
money, then rather than contradicting the law of
value the price of land affirms it!
25 Marx mentions his treatment of surplus-value inde-
pendently of its fetishistic forms (interest, rent,
profit) as one of the
three fundamentally new ele-
ments of’
Capitcd
(Marx to
Engels,
January 8,
1868).
26 See Morishima, 1973, Chs. 5, 6; and Shaikh, 1973,
Ch. IV, Sec. 4. In both of these, it is established
that there is a monotonic relationship between the
money rate of profit
Y
and the Marxian rate of
surplus-value
s/v,
for given conditions of produc-
tion. Of course, the Marxian value rate of profit
S/(C + V) is also a monotonic function of
S/V,
for
given production conditions. Thus the money rate
of profit is a monotonic function of the value rate.
27 The velocity of circulation of money is actually the
rate at which commodities enter and drop out of
circulation. But because money remains within cir-
culation, and commodities enter to be sold and
leave when consumed, it is the money which ap-
pears to cause, rather than measure, the movement
of the commodity.

44 As noted earlier, the location of uneven develop-
ment in free trade itself implies that we must be
more precise in distinguishing imperialism as a

opment as an immanent process in all stages. This

Weeks for pointing this out to me.
